gayer than ALWAYS choosing the line with the DIFFICULT customer who takes forever 
Gayer than noticing that customers in line in front of me almost always have the IQ of a turnip. Seriously, let the clerk ring your shit, pay, and get the fuck out... don't search for a coupon, argue over 50 cents, ask the clerk a stupid question she would have no way of knowing, or start writing a
check at the very end.
