When I attended Eastern Montana College in Billings (EMC), I think it was Sandy's (sp?) Drive-Inn that occasionally offered 5 burgers for $1 (usually it was 4 for a buck). The burgers were about the quality of the el-cheapo ones at McDonald's, but for a kid with no money, that was an awesome deal. Walk in with a dollar bill -- walk out with a bag full of burgers.
Of course, money was hard to come by, so after digging around in the car for change -- a decision had to be made -- hmmm -- purchase a gallon and a half of gasoline, or walk to Albertsons and purchase a six pack of "Generic" beer for 99 cents (if you are as old as me you know the ones, the white cans that simply had BEER printed on them), or go to Sandy's (sp?) and grab a bag of burgers, or perhaps go to the Casino Club (which ironically, was not a casino) and get 10 cent well shots.
Ah, the decisions. Unfortunately, more often than not, gasoline for my Ford Mach I Mustang came in last -- you could always grab a ride.
