I like it very much so I'm frequently in a quandary.
I say, "Brus-ketta" and then the waiting staff always correct me with "Bru-shetta" whilst sneering.
Have tried explaining that the "ch" sounds like a hard "k" in Italian as in "Chianti". Then they probably go and spit in my food 
Today a waitress kept on and on saying she didn't understand what I wanted to eat until I had to explain and when I used the Chianti example she didn't know what it was. Oh and then she said she was dyslexic (despite telling DH she was at University training to be a teacher) so I felt really awful!
Pedants, what do you do?
Do you use the wrong pronunciation initially and risk scorn or pronounce it correctly and chance being "corrected"?
Sorry for crashing your board with my shite grammar btw
