No Shoes

I had a coffee mishap this morning, meaning I didn't prep my coffee last night so when I pushed the on button nothing happened except a lot of noise of the water pump trying to suck up the little bit of condensation water left from the previous morning.  I decided on my drive into work I needed coffee.  I stopped at McDonald's.  I know.. I never eat there but i often will stop and get a drink.  I pull up to the window to give the man my dollar fifty for the large coffee I ordered when I saw the sign:

Drive Thru and Lobby

no shoes... no shirt.. no service...

I stared at the little self adhesive sign on the window and began to think.  How do they know if I'm wearing shoes in my car?  A shirt they can tell.. and what about during the summer when boys don't wear shirts?  especially at the beach.  Do beach McDonald's have this sign?  Nobody at the beach wears shoes or shirts.  Even bikini tops are acceptable shirts at the beach.  SO  I took my shoes off.  I was not wearing shoes.  And you know what?  I got my coffee!
