It goes something like this:
I arrive at Home Depot, noting a huge sign outside their door going on and on about excellent customer service and how they will honor their competitor’s coupons.
“Hi, welcome to Home Depot. Can I help you find something?” says the head cashier.
“Yes, I’m looking for a drive belt, please,” I say.
“Drive belt? Do you know what kind?”
“I’m afraid I’m not sure. I’d like to see what you have, though.”
“Okay. Let’s check our inventory for drive belts and see where they are…”
(Get lead to one of their many computers and conduct a search.)
“Ah, here they are. Garden department, last aisle. Would you like me to help you pick one?”
“No, thanks, I can handle that on my own.”
“If there’s anything else you need, let one of us know!”

But what really happened was:
I arrive at Home Depot, noting a huge sign outside their door going on and on about excellent customer service and how they will honor their competitor’s coupons.
“Hi, welcome to Home Depot. Can I help you find something?” says the head cashier.
“Yes, I’m looking for a drive belt, please,” I say.
“Drive belt? What is that for?”
“A small dryer.”
“Oh, go to appliances.”
Appliance dude says, “We don’t carry those here, let me give you the name and number of a competitor who has it. They’re up in Escondido.”
(Sigh. Wander store. Wander, wander, wander. End up in power tools section.)
Power tools chick says, “Those kinds of things are covered under warranties so you’re not going to find them here. Check our competitor’s store, they specialize in warranty parts. They’re near Balboa Avenue.”
(Sigh. Wander store. Wander, wander, wander. Buy small stuff I need and leave. Put small stuff in car and notice a massive potted plant sale in the garden shop. Browse. Decide to try one more aisle with displays of power mowers. Wander. Wander, wander, wander. Find drive belts. Find exact drive belt I wanted. Buy drive belt for $3.96.)
“You bought something else?” the head cashier smiles.
“Yes. I found my drive belts. After everyone said you don’t carry them.”
“Oh?” she replied with a look of alarm.
“Yep! And it only wasted two hours of my time.”
(Leave store, kicking huge sign on the way to the car.)
