It's Friday night and it happened again - in the middle of the rush the POS system is locked up and no one can take orders. I missed a critical order because it didn't print. I dread having to make menu changes - it will take me all day to figure out. Customers are complaining that their order isn't right - because the point-of-sale system just doesn't work. I can't start anything new - like online ordering - my POS system can't handle it. Heck, I can't even find hardware that's compatible. And every time I turn around I need to spend more money to keep it running.
