Stress
You could have an incredibly busy schedule if you work in a popular hotel.
If you work in a posh hotel with rich and famous clientele, then you could be asked to run errands in addition to handling everyone's valuables. You could be barked at, ignored, condescended to, or even spit on (if you're dealing with an extra-spoiled star).
If you break something or lose a suitcase that has precious jewels or expensive clothes, you could lose your job...but beyond that there's not a whole lot of important business riding upon you.
