And those who combine both functions:
Mr. Fu notes two Wal Mart greeter failures in the last three weeks. Crotchety old farts engaged in chatting with other old farts.
But that was all offset this morning by a singing greeter / valedictor. He warbled “Welcome to Wal Mart” upon entry for all the customers and “Thank you for shopping at Wal Mart” on the way out. The experience was different and kind of disturbing in an unfamiliar way. Perhaps if they employ more singing greeter / valedictors Mr. Fu shall become accustomed to their presence.
