The ones near me do have scales, in two places

* Analog spring-based scales in the produce section, for customers to check weights before they buy

* Precise scales at checkout, built into the scanner / register.

However, most things are sold by package — only a few are sold by weight.

Scales to weigh fruit/veg? No at leas not in Germany. The scales are built into the barcode scanner of the register. They only have scales so you can double check when you are shopping.
