Yesterday, I had lunch in a pub. I ordered my meal and a pint from the women behind the bar. She gave me my drink and I paid her for the meal. (I used a CC and there was a place for a tip but I left it blank.). When my meal was ready, she brought it to my table. When I was done as she was walking by she took the plate. I stayed to finish my pint.
I say this is standard pub operation and there was no need for me to leave a tip. (I've done this countless times.) My friend says I should have left at least 10% because she brought me my food and tipping etiquette is changing in pubs.
Was I right or was I wrong in not leaving a tip?
