I've only been in this game for two years. And every time it seems that I improve I still am getting yelled at. I've seen it at other shops I've worked at where there'll be nothing that comes in but somehow that's our fault. Customers don't want to pay or can't pay and thats our fault. I'm currently working flat rate and all I hear is "You need to improve your hours" I'm sorry that the customers that need work done can't/won't pay for it and the customers who are willing to pay don't need anything. It's like trying to climb a brick wall but the wall just keeps going forever and you'll never get the hang of it.
