Went to give an estimate on a spring clean-up with mulch yesterday. Customer told me that she wanted the same things done that we did last year at this time - which was weeding beds, mulching of a few leaves, first mowing of the season and to freshen-up the mulch. I told the lady that we would do it for the same price as last year. She looked back in her check register and said that we did it for $495. After I got home, I thought that didn't sound right. Come to find out that we charged her $595. I know that she is trying to cheat me! How would you handle this situation? Thanks!
