BigE1...you might want to raise your prices a little on the next one you do!
$5.00 for a sammie and a drink is good price and with a side of slaw a very good price, out here a side will garner $1.25 - $1.50, so with a sammie slaw and a drink you can easily make $6.00 - $6.50 and your 140 people work out between $840.00 and $910.00 up to a 65% gain for your pocket.
Just a thought!
