I have the same experiences when I am 1X years old.
I still remembered I go shopping with my friend in the summer holiday. My friend found a jacket so nice so went into the shop to try it. The sales lady is very nice to serve us (at the very beginning). When my friend expressed the jacket is not quite suit her and gave it back to the Sales lady, the Sales lady XZY both of us immediately. She also said don't let her see us again..... :-(
If this happened again nowadays, I sure we both will not just keep slient and let her blame....
