Go into Wendy's around 9:00 p.m.  Nobody in the store.  I 
ordered a Frosty.  The guy at the counter pushed the little 
button on his register and leaned into the microphone and said 
"Frosty".  He then proceeded to turn around and draw the drink 
HIMSELF!  I asked why he used the mike, and his response
was, "That's the way I was trained to do it.  If I don't, I get 
confused".
