How to take a break.
As a general rule it is always best to look busy, and therefore never look like you are taking a break. Your supervisors & the customer are constantly worried that they are being cheated. This is of course irrational & emotional, but never hurts to be considerate of others experiences.
Please take your break out of sight, between work locations, while waiting for others, or where you can fit it in without extra hassle for yourself or coworkers.
