(I have just started out) This morning, for the first time I had four customers to do. I normally only have one or two. I couldn't remember or record what time each one a expecting me. I got to my third customer and he said he thought I would have been there at 9 I was there at 10 45, he was ok and re-arranged for Wed morning. Fourth customer had gone out. These were all the first time I was to clean these customers windows and I just assumed they wouldn't mind what time I turned up as long as it was sort of in the morning, this was wrong right? I have a diary on my phone and it does have times throughout the day on it, is it important to make sure the customer is in an exact slot? If they don't care what time - leave them to last? Should i call the guy that wasn't in and apologise? Basically, I think I have time management problems! When arranging a time for the next clean should I keep my phone with the diary on it in front of me at that time so to see if anyone else is at that time? And should I ask if they want an exact time? if you are going to be late, should you call? If you need to shuffle times or days for them around, should you call and ask them, do they mind being called and having it changed?
