Unfortunately i was right. Humor is dying a slow tragic death in this country.
The store is owned by a husband/wife team. Weather you are buying your first gun, a long time gun owner, young, elderly, male or female, they will spend as much time as necessary to help a customer make the right choice. They only offer facts, not opinions. Even when they know the customer is just a tire kicker (if you've ever worked in retail sales you know it's fairly easy to spot tire kickers) and has no real intentions of buying the specific weapon they just asked to see, they will still treat them as they would a paying customer.
The customer is a retired school teacher and weather see got the joke or not, she was not offended by a simple joke. Even though the store was fairly crowded the clerk spent quiet a bit of time showing her different types of pepper spray and even gave her a few tips on how to use it. She left the store happy with her purchase.
