Working breaks are nice. On the other hand, you have to time them well, because if you time your break for right in the middle of a rush you might not get much of a break at all.
Bagel Hell forbade eating behind the counter, but we could drink coffee. Every day I would fill a coffee cup with soup (as long as it was something like tomato or chicken noodle, so that there was some broth) and drink it while I worked. The boss/ownerman never asked about it, as long as I wasn't favoring my own "coffee" over customers'.
