Hi, One of my customers that normally gets charged $35 per visit... We didn't cut the front half because there was a lot of construction going on, On the back half we kept doing though. He wrote me an email that I'm killing him with the bill. "Lets settle on $20 per cut for June and we can return to the $35 full price now that you have started to cut the front again." Should I Lower the price or say that price is same. What do you guys do on these situations?
