About to quit

I’m going to have to quit my job soon. With the amount of churches ordering from our restaurant, I can’t afford to pay my bills. We took a 3,000 dollar order to a very wealthy community, let them borrow our cambros, they didn’t give us a tip at all. I’m so disappointed its ridiculous. I was raised a Christian and I think every day how that was a waste of my life. I think Jesus would be disgusted at the way churches treat catering, delivery, and restaurants.
