Beer's in Santa Cruz

Spotted at Hoffman's Bakery in Santa Cruz.

"Fluffy Three Egg Omelet's" are featured on their online menu.

Margarita's

Seen at the Pappasito's Cantina in the airport in Houston, TX. Oddly enough, the printed menu and chalkboard renderings of "margaritas" didn't include the apostrophe.

Egg's and Tomatoe's

At a cafe called Circle 8 around the corner from where I live in Newtown, Sydney Australia.

What possesses them to think that 'eggs' needs an apostrophe I wonder? And why no apostrophe in 'mushrooms', then?

(Thanks, Peter!)

Mind Your Ps And Qs Or Your P's And Q's?

I hope you can settle this dispute. I teach high school and the cheerleaders painted a banner for the hallway. It reads, 'Lady Q's drown the opposition.' 'Q' is short for Quarriers; the town is known for its quartzite quarry. I maintain that there should not be an apostrophe after 'Q.' After some research online, in the school library and a couple of textbooks, we were unable to come up with a conclusive answer. Can you resolve this?
