It's also problematic for the thousands of solo micro-businesses that operate in markets and pop-ups now (i.e. Etsy IRL). Most of them have a phone and a Square dongle, and that's it. Asking all those one-person shops and merchants to start carrying around a float and writing out paper receipts (or having some kind of battery-powered till+printer) is a pretty big burden.
Stores have been doing this since the dawn of...stores. Or at least when currency was first invented. There are very established processes and practices for this sort of thing. It's a cost of doing business, in the same way people pay for rent etc. for their stores.
Right, but now there are more efficient systems (the aforementioned Square dongle). We usually welcome technological progress that reduces costs, why opppose it in this case? The colourful pieces of paper and specially squished lumps of metal have been obsoleted. The solution isn't to force people to keep using cash, it's to make an electronic money system that has the good properties cash has (issued and backed by the government; directly tranferable between payer and payee; mostly anonymous but theoretically traceable in case of massive theft/fraud).
