Bullies here will attempt to impose a minimum purchase fee for debit cards to get you to spend more. Report them directly to Visa and MasterCard processing networks as they are not permitted to do so per their contract with both companies. Don’t accept this nonsense. Report them and then shop elsewhere while you’re serving on jury duty. Reporting merchants uses a very simple online form, and takes only 30 seconds. Maybe some fines will make them change their ways. All I wanted were some donuts, and now look what you’ve done.
