Avoid the soap opera
Avoid the hierarchy. Every competitive industry has back-stabbing co-workers. Be polite to everyone, don’t repeat gossip, and lock up your items. Thieves lurk everywhere!
And PLEASE don’t fall into the trap of dating your co-workers or bosses. This rarely works out well.
Your time and labor come with a price, because that's how transactions work. Practice saying, "No thank you, I'm not going to do that." Clientele will try to haggle you for prices, touch you more than is allowed, or simply refuse to pay you.
Remember that your time is an asset! You as a worker are able to refuse service, especially if someone is indicating that they don't respect the house rules or your personal boundaries. Get the money first if you can. And if the guy asks (and they will), "You don't trust me?" that's when you smile and bat your lashes twice. "I don't trust anyone, silly."
