People , like myself have feelings .. Some I will like and some I won't. Same with people ...it's thier opinion plus they don't have to like me so what they say doesn't matter.
You find a hair in your dish in a cafe - what do you do?
Just quietly tell the waiter and ask them to be careful . And the choice is not to eat there again...bcuz of the disgusted feeling. Yet again it can happen any where else.
