Stick by your guns. Your pizza is obviously tops. You are dealing with teachers, right?? I would think so, and teachers are the worst of the worst as far a cash is concerned. I know it sounds like a generalization, but 30 years in the business has shown me that it is a just generalization. Teachers are tough....but, the gravy train has passed. A buck fifty for a slice is absolutely fair. Their just ticked they dont have a bargain any longer ( at a buck fiddy, its still adeal). They will simply have to get used to it. Believe me, those that leave will realize that a buck fifty is STILL a cheap lunch and they will be back.
Walt, you know, your situation differs from a normal commercial setup. I can bet my life that most of your customers see themselves as MORE than CUSTOMERS....that somehow, they are in a different position than a normal customer. They feel they SHOULD get special brakes, becasue they are employed by the same people as you, right?
I worked at espn. You should have heard the complaints on FREE coffee and 95 cent PINTS of soup (we were contracted as a non profit unit). They simply saw the ESPN cafeteria as a BENEFIT to their employment, just like insurance and all. Any hint of you trying to balance the books looks to them as you gouging. Its pretty commen. But, the good news is that they get used to change, after a while.
Sorry about your situation. People look at food service operations as DIFFERENT from most business anyways. And it gets toughter if your involved in a food service place within a closed enviornment. But don't worry, if your prices are fair, your quality is good, your service is supporting, people will eventually fall in line. I have no reason to beleive you are anything but an asset to your situation. It will work itself out.
