When I was working for TCX, we had an asian family heading off for a week in the sun.
The father of the family asked for some hot water. Being crew, I was obliged to bring him it. It was for one of the cheap, fake Pot Noodles you get in ethnic supermarkets.
Not kidding, but his hand luggage (which was larger than it should have been) was PACKED with these noodles. He offered us all one when we had a chit-chat about the volume of noodles he had to take with him.
Sure enough, 3 of the 6 crew accepted the offer, and chowed down on what were better than expected noodles.
Thankfully we were still concious in the following hours, but the rewards outweighed those risks for sure.. such a pleasant change to the "beef cobbler"
