TGI Fridays are really hot on sending the manager over, aren’t they? Went years ago and there was something slightly different with what I ordered compared to what came out, but wasn’t a huge deal. Think I mentioned it politely, and said I was happy to eat it if it was any problem etc, and the waitress immediately got the manager over who was really disproportionately apologetic (not in a bad way ofc) and knocked it off the bill or gave free drinks or something.
Was quite impressed, but must be a bit shit for the staff and lead to loads of customers trying to game free stuff
