I am an older man, 51, with littlle income, do free ministerial work. Possible menial work?

The restaurant will not hire you as a busboy. It isn't fair but they only hire teens as bussers. You will have to start as a dishwasher. They will hire you for that. Whenever one of the busboys or waiters is sick, offer to come in on your day off and work that shift. The boss will soon see that you are the right choice to wait on tables. YOu can make good money doing it..
