I'll take marc's point that there is no overselling, and give that to you. My employees would do the same as me thats how they have been trained to deal with customers, like I said I give the customer all the options all the time and then get a feeling from there feed back. If that was my customer and I told him all the options and he asked, "Would i be better off replacing this" I would reply, "Yes but not today, today I will fix it and you call me this week and we will set it on the schedule for replacement, It is going to cost you $X, when I come back." I think you know all the variable of the conversation. What it comes down to is the guy needed his power on and it was Sunday.
