The times when accepting card payments was expensive have been over for years. Everyone whining about "card payments cost so much" should look what the combination of pricing caps and competition have brought up, especially with the pandemic.

Customer retention is not a problem if people are used to cash.
Transporting and keeping cash is still a thing if you accept cash. Accepting cash and cards is just doubling costs and logistical issues.
In France at least.

I think that for food businesses in brick and mortar shops in France, if you take cash, you have to get a cashier's machine. Not 100% sure that's true but that's the explanation i got from a bubble tea shop who didn't take cash.

Even tiny food businesses have quite a few transactions in a day. Wit weird sums that may make cash painful in other ways. €6.71 is fast by card than counting coins and queue length may matter at peak times. I was talking more about, for example, hairdresser where amount is square and there're very few transactions in a day.
Technically yes, but the cost that Sumup or whatever else processor you use gets charged is based on a percentage amount set by the card networks. Sumup just adds a .5 or whatever onto the rates they get from the card networks and there's the .9/1.9% final charge.
