When I overheard one of my cashiers tell a customer,
"We haven't had any for a while, and I doubt we'll be getting it soon,"
I quickly assured the customer that we would have whatever it was she wanted by next week. After she left, I read the cashier the riot act.
"Never tell the customer that we're out of anything. Tell them we'll have it next week," I instructed her.
"Now, what did she want?"
