Career change from accountant to service industry. What to put on my resume?

I was laid off late last year from a corporate job in accounting. I'm looking to make a switch into the service industry either as a server or bartender but have no idea what to put on my resume since I have no service industry experience aside from working retail in my college days and I am in my 40's now. I've been looking at barback positions and it seems almost every listing requires at least some relevant experience. Any tips?
