The involuntary facial reaction produced by payer of
bill upon observation of bill at
time of payment at a restaurant or
bar.
This is discernible due to sudden albeit momentary change of facial reaction that is often masked by bill payer's efforts to divert attention by loud speech, reference to other events, reassurance that bill amount is far less than expected,etc.
This reaction
may be excessive due to unexpected amount or ever so slight even if the said amount was presumed. This reaction is only involuntary and genuine on the face of actual payer at the
time of bill payment and will occur with certainty upon bill payer's face 97% of the
time regardless of financial status.
As Mark and his closest
friends rounded off the evening laughingly, hardly anyone was the wiser as Mark suavely opened up the check folder and experienced momentary billface.
One of Mark's
friends Dave did mention to another mutual
friend Lisa:
"Hey great evening we should do this more often, next time it will be my treat (secretly thinking heck no) but I'm glad Mark is treating us today ..here comes the check..watch for it ..watch for it... BILLFACE!" as he & Lisa quietly snickered in the corner.
Mark quickly paid the bill and began to mention how he will have so many stories to tell his co-workers tomorrow (trying
hard to disguise his bill-face effect).
