Bavarian bakery spends 15,000 euros on precision scales after customer dispute over ten grams of bread

The ten-gram dispute in Pfaffenhofen

In September 2025, a customer visited Bäckerei Breitner in the Upper Bavarian town of Pfaffenhofen an der Ilm to buy half a loaf of bread for 2.40 euros, exactly half the price of a full loaf. For more than 60 years, the family-operated business had routinely cut loaves in half at the counter and charged half the price without weighing the individual pieces. After reweighing the bread at home, the customer returned to the store in anger, demanding the full amount of product for the money paid and claiming the half loaf was roughly ten grams underweight. Unable to resolve the dispute, the retail staff called the owner to the front of the shop. Master baker and confectioner Mathias Breitner initially dismissed the complaint, remarking that customers sometimes win and sometimes lose, and suggesting the customer might receive 20 grams more on the next visit.

Breitner later acknowledged that his reaction had escalated the disagreement.

That was my mistake. I should have simply given him a loaf of bread.

Regulatory enforcement and packaging rules

The dissatisfied patron left the store warning that the encounter would have consequences, and the bakery subsequently received an anonymous complaint by email. Weeks later, inspectors from the weights and measures office in Ingolstadt arrived at the bakery. Officials prohibited the business from selling half loaves at flat prices unless every cut portion was weighed on a certified precision scale and priced strictly according to the designated kilogram rate. German packaging law under the Prepackaging Ordinance, in effect since 2020, specifies that whole loaves from the oven qualify as prepackaged items with predetermined weights, whereas loaves cut on demand at the counter can vary in weight and must be weighed individually. Breitner noted that he was previously unaware of the requirement. Stefan Thums, director of the Bavarian State Office for Weights and Measures, outlined the legal principle behind the enforcement.

Whoever sells something by weight must weigh it beforehand.

Thums stated to Bayerischer Rundfunk that inspectors conducted a routine visit to calibrate the shop's scale, which was no longer on site, though other accounts linked the visit directly to the customer's formal complaint.

Technical overhaul across six branches

To meet regulatory standards, Breitner overhauled retail operations across all six branches located in Pfaffenhofen and surrounding areas. The bakery equipped all nine checkout counters with calibrated precision scales, purchased specialized software to link the scales to cash registers, and conducted training sessions for counter employees. According to Breitner, the investment in hardware, software, working hours, and staff training totaled nearly 15,000 euros. The regulatory enforcement also impacted other local businesses in the municipality, where another bakery temporarily halted sales of cut loaves entirely before eventually installing certified scales of its own.

Pricing shifts and cash register impact

The mandatory weighing system brought an end to decades of simple flat-rate pricing for customers buying half loaves. Whole and halved loaves are now priced by exact weight at checkout, resulting in uneven amounts such as 4.78 euros or 4.83 euros per loaf. Because most patrons pay in cash, register drawers regularly overflow with one-cent and two-cent coins. While several regular customers have asked to pay rounded flat prices to simplify transactions, Breitner refuses to deviate from scale readings to prevent further regulatory violations. The customer whose ten-gram complaint triggered the inspection has not returned to the bakery.
