Sounds like a disaster waiting to happen, too. We had Maitre'D crash on us one year later, and we had NO backups at all. I just thank god we kept at least hard copies of all the financial stuff. I got stuck with reprogramming the menu, ugh. it was **** for a week, with servers hand writing dupes, and calculating all the totals with hand calculators.
Technology is great when it works, but always keep backups, digital and hard copy, and don't fire your expeditor just because every station has a touch screen all of a sudden. When the system goes down, as everything is bound to do in the kitchen one day or the next, you don't want to have to close your operations while it's being fixed.
Oh yes, as for curling chits, yes the only way to keep flat is creasing them. Also, I've noticed that the closer they get to the end of the roll, the worse the curl gets, so I sometimes change to a brand new roll right before a heavy service so that I don't have to spend time fighting with the curl of the bills while the world is ending around me. I use the ends of the rolls for sleepy monday-wednesday lunches etc.
