I'm guilty of that. Not trying to come off as a jerk but I will prioritize a customer that is a commercial account. I understand that a customer is a customer whether its a $130 string trimmer or 20 MS 461's but if I have a large account I will absolutely put them first for a few reasons. 1) From a business point of view, I cannot simply afford to loose a big account like that and keep things going. Now losing a $130 sale, meh, yeah it sucks but it happens. I understand that you do that 3 times a week it could catch up fast. 2) If a saw they need repaired comes in, that is there income. That is how they support their families. I can respect that as this is MY income as well. If you have some firewood (and I am not degrading your task in any way shape or form) if you can't get to it because your saw is down, its just a PITA and an inconvenience. 3) Most commercial accounts are quick. They want the work done fast, no matter what the expense as they rely on your knowledge and trust you to make the best decision for them. Someone who comes in for one or two repairs a year TENDS to be one that takes more of, "Is that the cheapest way?" or "I can find the same part cheaper online." I don't have time for that run around stuff. I'm sure there are a few other things I'm missing right now and I understand there are two sides to every story. I just want to point out that we are also a hardware store, grocery, feed, and lumber yard. This IS our busy season. I am backed way up I admit. Between getting caught up and trying to help out in the rest of the store, Its frustrating trying to get started working on something then get pulled off it in 20 minutes to go shag boards. I find the room for error increases so I sometimes don't bother getting started on something if I know its an in depth project until I have sufficient time. I can't afford to do things twice because of a dead short in my brain.
As far as servicing only what they sell? I've moved back to that. I prioritize stuff this way. Commercial, my brands purchased here, my brands, pro brands, miracle work. I used to do that; whatever it is, bring it in. Then we had garage sale day and I had a floor of $20 piles of crap that they bought used at a garage sale for $5 and now they want a miracle. I'm no miracle man, nor do I want to be. I've gotten to the point where I only find it fit to turn down small work. So going back to a setup like your MS 270 problem, MOST shops are charging $65-75 an hour around here. Stihl manual says 125 minutes to which is at the minimum $130 bananas. I have a hard time charging that much for a saw that is worth about $175-$200. So as guilty as it sounds I don't prioritize it because I feel that its hard to justify the repair and telling someone that their saw isn't worth it ends up in a 30 minute convo of trying to explain why a product isn't fixing... blah.. blah... As sad as it sounds its a cruel circle.
