/u/ZookeepergameNo7151 on Today, I ordered takeout and picked it up at the register. The tap and pay came up. The tip portion option was either 18%, 20%, 25% or other. I choose other. I did 10%. The lady looked pissed and asked “why did you change it to 1

Wait 5 sec.

Shouldn't have tipped anything.... What did they do that was out of the ordinary I'm between processing the order and bagging it?
