Great points Arlyn!
The most interesting comment that I heard this season was someone asking me "Would you like me to pull this thistle? You know they don't have thorns near the bottom?" I politely declined their assistance...
My two biggest pet peeves have been, as Bonnie and Tom mentioned poorly supervised little children and the occasional person who does not show up to pick up an order that I have dug, cleaned, trimmed and labeled for them.
