7. Not removing all your crap from the table when the food arrives
Your bike lock keys, bike lock, American Spirits, sun glasses, phone, wallet, purse, e-cigs, vape pens, and whatever else fits in your messenger bag can remain in your messenger bag.

Congratulations, you exercised. It's not an excuse to make like Belushi in the Faber cafeteria.
