What Happened To Me At Walmart Has Me Feeling Stumped

I tried to use the self checkout at Walmart. I just realized that I'm stumped. I really am.

The line behind me made me nervous.Sweat. Panic attack. Fear that i would unintentionally shoplift.

The last time I felt this stumped was my first time using Red Box to rent a movie.

Next time the lines are long at Walmart,with only 2 checkouts open,I will patiently wait my turn.
