"Is $25.32 OK?"
I try to read the situation and face(s) and continue (if a quizicle look or a serious look of concern)...
"It asks me here .. Is $25.32 OK?"
It doesn;t matter at this point what the looks or disposition may be ... I continue;
"The obvious answer is ... How do I know" ?
Let whomever say what they will say and follow it all with;
"Would a Socialist Muslim illegal alien be good as president of the united States ? .... (slight pause) ... don't ask questions ... just push yes or no.
I haven't been beaten up yet and only one or two didn't appreciate the comment.
Teens just look at me and have no clue.
Try it ... the public is fun.
