24. Be a Secret Shopper
Of course, when you're a secret shopper, you don't have to do anything.
You get paid to stop, you generally get reimbursed for whatever you buy, but your main job is to critique the store you visit.
You have to pay close attention to the salespeople, the atmosphere, the selection, and so on.
There are some sites that will send you to other places to score them as well, like nursing homes, doctor's offices, and things like that.
