Not so much a thick passenger comment but quite funny.
Years ago on a flight out of LHR we had a large party of young language students.
One pressed the call bell and eager to try out his newly learnt English skills he asked the Steward in very heavily accented and laborious English "Pleeze I would like a glass of orange juice thanking you"
The steward in complete dead pan mode lifted his left arm looked at his watch and said " ten past three".
The expression on the poor lads face was amazing and you could see his lips moving as he silently tried to remember the correct words!
