Today isn't my day for the advice, but i thought i would offer some advice anyway.
Do not get drunk at lunch, and return of the office in the afternoon like all is normal.
Though this can be fun, it is also very difficult to pull off without getting busted. i got fed martinis at lunch yesterday, returned to the quiet office, and apparently smelled of booze and talked really loud.
So, avoid doing this if possible. hey, sometimes it happens, i understand.
I have no good quote, but someone can help me out here.
