I had a race car owner who wanted to change his number only on the car today. He said you have a month to do cut vinyl for my new number. He will apply. This reminded me if the last customer(a year ago) that had a mini race car last year. A few numbers he would apply. With a shadow. I said 75.00.. We measured it. 6' numbers. He mentioned that the last guy who did it worked out if his van and did it for 25.00 . I said that was cheap , but I have overhead costs. He agreed and paid in advance. When he picked up the numbers he measured the numbers 2 were 6" and the first one was 6 3/16 tall. It was the font that made the variation. Would you refund - stick to your guns or re do ? I think he wanted them for free. Its a dumb small job, but many times this stuff can be a pain
