Funny thrifting story:
I was in a GW in Houston and I stumbled upon two crescent wrenches, one was 1 3/8" and one was 1 3/4". I picked them up and was thinking of what to do with them when I realized that they were perfect to keep in the truck for self defense (at least the 1 3/8" was - the 1 3/4" was too big and heavy).
So I'm swinging it a little when an employee walks up and sees what I'm doing.
Him: (unsure of what to think) "Finding everything alright?"
Me: "Yeah, everything's good."
(he leaves and walks up to another employee)
Him to the other person: (whispering, but loud enough for me to hear) "Don't f*** with that guy."
End note: The 1 3/8" fits perfectly between my seat and console and is perfect for plausible deniability with cops. Never had to use it though... The 1 3/4" is going on the wall in my man cave.
