Booked car for MOT always concerned about being a single

Booked car for MOT always concerned about being a single women being ripped off. And although my MOT should have cost 29.95 pounds I was changed 35.00 pounds I do believe this was a genuine mistake and I never realised until I got home. However my bulbs were gone and they could have said this was electrical but they were very honest my MOT therefore cost me very little and I felt I could trust these guys. Little place to park but a nice room to sit and wait in. And also I left my bag underneath the chair and forgot and they were honest to tell me I’d left it there. Would Defo use again.
