Customer 8 (good? i think)

Customer came in, older guy with a phone issue. No problem! 5 min later its fixed and all is well. Well he is not satisfied, he decided he wants a new phone. Again no problem hes being nice lets get him a phone go over options and get him gone happy. He does not want any ties to us so he goes ahead and buys a phone at full retail value, which is interesting because not many people do that but ok no problem. We set him up with a budget phone which for those who never herd that term before basically is a cheap phone made with lower specs for people who don't need or want the latest and greatest. It cost him $240 and hes on his way. I see him a month later with problems on his phone (basic things like moving icons around on the screen and turning on wifi). We get things taken care of and he leaves again after telling me a 30 min long story. Comes back in the next month with some similar issues, and again we fix it he tells me a 30 min long story and leaves. The 3rd time he decided he wants a new phone again and buys the newest galaxy we have. Lovely sell it to him for the full $650 as requested, set it up and transfer data and another long story and he leaves happy. No this guy is very nice however he has already used up around 5 hours of my time at this point and when i sell something at full value i do not make commission off of it so i'm losing money talking to him. And he continues to come in every 2 months or so for a quick 5 seconds question followed by a 30 min story. To this day i have made all of $2 off of a case he bought from me and worked with him for maybe all of 45 min and talked with him and his life story around 10 hours. Very nice guy but i don't get paid to sit and talk, although i don't mind talking to him when you work on commission it changes your perspective and makes you feel used and it makes you feel like your paying him to talk to you. So he has been nothing but nice which is why i say hes a good customer i just wish i didn't get a life story update every time. So what do you think? Am i just being stupid for not wanting to talk to him 30+ min each time? Do you think hes coming in just to have something to do or is he actually trying to learn things? Comment below.
