Just wait until somebody pulls up beside you at the red light and wants to borrow some.
If somebody in a Rolls Royce pulled up next to my old pickup to ask for some Groupon, The Little Dog would probably come flying out from the back and sail through their open window, eat all their sammiches, then jump back into the pickup to ask me for a beer to wash down the sammiches.
That’s why I don’t carry beer in the pickup.
The stinking little booze hound would drink it all up and then stand with his front paws on the tailgate singing “Carolina Moon” or “Le Boulin”.
