Knowing how bad is the economy today (since when did it improve?), I will easily decide on taking the bonus. I'm very sure my co-workers will agree with me. We always have fun, anyway, so an office party will not be missed that much.
The office parties I have been to have been pretty ordinary affairs people seem to get into their nice safe little groups. You will see the grovelers surrounding the boss telling him things he wants to hear including praise for himself. Then you'll get groups of men congregate. You'll see the ones that love the Grog and the ones that love football get together in smaller groups. sometimes defined by age group. There is always an air of tension until attention is paid to the person that behaves the most badly.
