A lady just walked over to my desk to tell me she had birthday cake. So I walk over and snag a piece. Wouldn’t want it to go to waste, of course.
As we are talking I ask, “so how old are you?” She makes a strange face and says, “I’d rather not say.”
I’m thinking that if you bring in a birthday cake for your own fucking birthday, you don’t have a right to make a puss face when someone asks how old you are.
I prefer raiding corporate events for meetings I wasnt invited to. We are fortunate enough to sit right above one of the largest meeting rooms so we smell all the food as its being setup. Sometimes we are able to sneak in before the event starts or sometimes we will go in right after everyone else starts eating. As long as we have our badge and act like we need to be there, no one ever bothers us. I’d say that I get free meals and cookies at work at least three times a week. Its one of those hidden benefits they dont tell you about when you get hired. I hear you about the cake though…. when we raid the smaller gatherings with less food, we get dirty looks. Not the same as asking about a birthday, but you do get a weird look when stuffing your mouth and asking a stranger what the event is for. 
I hate it when people do that!
