In the other thread, I had mentioned how I sometimes bring a box of Timbits (Tim Horton's version of donut holes) for the crew when departing YYZ. The crews seem to really like them and share well. I figure its a bit of a unique treat too, since Tim Hortons is in very few US locations, and the crews tend to not leave the aircraft in YYZ, as they mostly turn back to the US within an hour or so with the same aircraft, except on the evening arrivals when they are overnighting.
And as I also pointed out there, I don't do it to get treated any differently, and don't recall having been except having various crew members come to my seat to thank me. I do it because I understand that life as an FA is not as glorious as many seem to think it is, so just a little thing that hopefully can help make their day a little brighter.
