I got "screwed" last night

In more ways than one:
Driving home after dinner wife and I hear a "thud" coming from my car(did not hear b4 dinner). Got home and there was a very large headed bolt/screw in my rear tire. I went to local Michel tire and they blew me off bc close at 7 they still had an alignment to do on another car and it would take them up to closing time and tire was not flat yet. this was at 6:40. Guy came out and looked at tire(not flat yet and saw the screw and said he could put a spare on it for me) I told him this is an Eco that doesn't come with one even tho I bought one and that was not an option. So I went around the corner to a Tire discounters and they said they only had one tech working and blew me off also(Chip wood would not be happy) but could make an appointment for today and suggested I go to Tire discounters on another street. I went there and on the way the screw came out and I was able to make it to other TD and they patched the tire, I told them what happened at the other TD and they were surprised only bc they had the same one tech working. I would say the first one had "crappy management" this is a new TD location by the hwy. Tire discounters(corporate) will hear about this in a comment about how stores are run! Even tho they make more money they have bad management at the new location. I have @ 35K on these tires and not sure when to replace. I replaced first set about 36K. I think w/in 10K I will be in need again. I know which tire stores I will not go to!!!! Any ideas as far as tire replacement?(Continental, Bridgestone Goodyear etc.) I was wondering about Cont. Pure Contacts, those seem interesting they I hear a lot about other name tires like Kenda, Hankook, etc. but know nothing about them.
