I think often with giving electronic tips the money just ends up going to the company, I know people who have worked in restaurants like thisIt’s maybe easier for them with tax returns but it’s not superior. So long as they give you a receipt it should be easy for them to complete their tax return anyway.
Everyone’s different with money and I don’t begrudge anyone who prefers electronic payments but I don’t think a cashless society would work for me and many others. I only really use my card for bigger transactions where I’d feel unsafe carrying a large amount of money. I also feel like a lot of people miss out on tips when you don’t pay with cash like delivery drivers, hairdressers, restaurant staff etc. I know some industry’s have included a tip option by card but many people are probably going to be more generous if you’ve got change in your purse than rounding it off to the nearest pound or something for a card fee if that makes sense.
