whats a working lunch and how do i deal with one? I have to go 2morrow but i dont know wtf it is or what i have to do ... i know that there are lots of profs etc,... TIPS?!?!?!

don't have spaghetti ;-)

Well, be prepared to explain your project/results to the others attending. Go to your supervisor and ask him/her if you are expected to show some of your data (if he/she hasn't told you yet this seems unlikely, though).
But you could just as easy end up with a table full of profs reminiscing about conferences they attendet, etc.

Don't worry too much, look interesed at all times and don't order spaghetti!

Get mildly pissed and use lots of long words

Wine?? You lot obviously have better working lunches than me!

In my experience, a working lunch is just a normal research meeting but with sandwiches!

I WAS coooool. it was sandwiches and fruit.
