I am making a cake for one of my husbands co workers for his 30 year anniversary at work. Im at a loss for what to do for a guy.. any suggestions??? He really isnt into anything, the job is pretty basic and they want a single cake (no tiers)... Any help would be greatly appreciated.

How many people is it for, ie does it need to be sheet cake size?
Maybe just write "30 years Congratulations" or something and a pretty border?
