Do you guys hate getting tips on debit/credit?

Long story short I stopped in a brewery unplanned so didn't have any cash on me. Its a Thursday afternoon so there were only a few people in there so I'm sure the guy wasn't making much. Anyway I added a tip with my debit card. Do you guys hate when people do that? Also I don't see any charges for the tip in my bank account do those usually come out separately? I think they used square or something
