I give away money like that, gladly. I don't mind paying for the service
because I no longer have to count up and bag up hundreds of 1p, 2p, 5p and
10p coins.

Anything larger gets used as normal, or bagged up and taken to the bank.

I did boggle at the lady in front of me who tipped in £160 worth of mixed
coins, with £1 coins being the most common (she showed me the receipt).
