Well, have started serving FT after only doing some temp stints over the last few years. Most of my experience has been in a (busy) small restaurant where there was no computer (just hand-write a ticket for the one cook) so it's a bit of an adjustment getting used to being in a larger-capacity restaurant with only one computer to put in orders, often with a hostess on it most of the night, and making sure the printer is working and the pasta station got the order etc.
So - what to do on the unfortunate occasion when you realize "oh sh*t I just told these people their food will be up in a few minutes (classic line) and I forgot to put in their order?" I apologized sincerely (without telling them it was my fault... for reference, they saw me running around, obviously busy, but also probably saw a table who came in a bit later get their food much quicker) and brought them a free round of wine, but needless to say they weren't happy.
What else could I have done to smooth things over?
Sigh - feel like a noob all over again! Gotta get back in the groove!
