Not sure if I am being unreasonable or not.
It's 2018 and almost everyone used a debit (or credit) card to buy things.
I very rarely carry cash on me.
I point blank refuse to shop anywhere with a minimum total spend to be able to use my card.
Example; I'd fancied a specific type of chocolate all day and had a fairly rubbishy day. Went to shop with £1.05 in change (!). This chocolate is usually £1. It was £1.20, so I went to use my card, but no, minimum £5 spend. So I put the chocolate back, and the guy said he had other types for £1, but instead of giving in and getting one, I just said no thanks and left.
I'm sorry that it costs you to have a card reader etc, but other business also have extra costs associated with the modern age, such as WIFI or other softwares.
It's part of the cost of running a shop so face it and swallow it.
AIBU?
