I was late into Amsterdam a few months ago, missed connection to Cape Town. KLM were overbooked for the next few days, so had to buys flights with BA via LHR. Was a nightmare day, was stressed and exhausted when we got onboard at Heathrow. CC asked us if we were ok, and shortly thereafter brought the drinks cart down and said "help yourselves!". We duly did, slept all the way there, and made sure to thank her on the way out. There's plenty of great crew out there, you just don't hear about them. Noone's interested in good news...
