When I go to lunch here at the company I always grab a bunch of napkins and put them on my tray, but I only need one or two, so I end up taking the rest to my desk and keep them there.
Up to now I have about twenty napkins (looking at the pile, I guess it's even more) piling up on my desk.
So, if you ever need one, I got one.
On a side note I wonder, will they catch me and fire me for repeated napkin thievery? They can't do that, can they?
