What is the meaning of "wait a few tables" in the text below? As far as I can deduce it would mean working as a waiter, but that doesn't seem to make sense within the context of the text - or maybe I'm not able to see the context in a broader way. Can this expression have any other meaning than the one I am deducing?
- Be willing to change the plan. Perhaps your dream is to become a famous visual artist. However, through your volunteering, you are asked to assist with some administration tasks at minimum wage. Do it! Sometimes you’ll make contacts in the most surprising contexts, and sometimes you might discover that diversifying from your original plan gives your business added opportunities to reach a wider market. And even if you need to wait a few tables, answer some phones or file some papers for a few months when nobody else wants to, if this helps you keep going and pays some of the bills, it’s worth it. Dependability and consistency will give you a head start whatever you do.
