If you need to earn a few extra dollars while you are waiting for a regular, full-time job, you might want to see about working part time in a grocery or department store as a sampler. I don't mean taking samples, I mean giving sample products to folks.
I'm sure you've seen these people, asking if you want to try out the newest perfume or take a sample package of some acne products, or even a taste test of a new cookie or sandwich meat. Those folks get paid and they aren't part of the regular crew at the establishment. That's the reason why you'll often see retirees doing these jobs. They are just a few hours a week, they don't take a terrible toll on the body, and they give the person a chance to get out and earn a little supplemental income.
Along those same lines are door greeters. The biggest discount store in the world uses door greeters. They say hello and they say goodbye, if they are doing their jobs right. If they've been there long enough, regular customers know them by name and they recognize regular customers in return, which makes folks feel good about shopping there. Door greeter can be a full time job, but it's usually not. This job is shared by a number of people who are only working part time.
