Business Leadership Situation?

Sunday, 10:00 a.m., store opened, about a dozen people were shopping. George & Ginny casually go up and down the aisles filling their basket and 45 minutes later end up at the register where they are sadly informed that the "computers are down and we cannot check anyone out. They have called the main office." In the meantime customers are coming and going. George asked if the wait would be long because he didn't want to put everything back but also didn't want to wait for several hours. "We don't know, we've closed the doors and aren't letting anyone else come in."
Ginny offered her great idea of simply writing by hand the SKU identification number of the merchandise and the cost, then adding it up, adding the tax, and letting people check out, "the old fashioned way." Everyone chuckled and continued to wait. Finally, George asks if he could at least put his name on his merchandise and ask them to call his cell when he can "check out."

What would you do as the store supervisor?

Determine how long the computers are going to be down. George isn't going to :"put his name on the merchandise". He's going to leave and go to another store and get what he needs, there. Most customers aren't going to wait in line for things to be done "the old fashioned way." I wouldn't. If TECH support can't solve the problem, quickly, then you're screwed, and you need to shut down. A lot of thieves would use this time to shoplift.
