I had a customer call today to ask me if I could come and cut her lawn today (Saturday) or Sunday. She says that she has some friends coming in and wants it to look great. She is normally an every other week customer that i charge 50 per cut. Her normal day is Friday which will be coming up this week. What do you guys propose I do in this situation. I must comment that she has been a great customer, no complaints from her, and she pays in record time every time. Should i add in a convenience fee and charge then also cut on the regular day or should i do her this favor and skip her next day. Thanks for your help as always guys.
