I'm going with the back-to-the-radio-shop option; if they're installing on a vehicle, one has a right to assume they know what's safe and what's not.

Having said that, a 107 is a car that a lot of wrenchbenders don't know anything about, leading to the need to know the vehicle yourself. Knowing where the tank is would automatically lead you away from allowing anything to be screwed into the front trunk wall where a point is heading blindly toward the tank. Yes, they should have known better, and yes, if they're professional they're paid to know what they're doing--but as owners, we do need to know enough to defend ourselves! And it may be simply that as a long-term inboard boat type I get really twitchy about any possible defect in a fuel system, but I'd not be very confident in a repaired tank unless a truly professional shop did the work; a leaky tank sitting over a nice hot exhaust line isn't what I want going on a yard behind my precious butt.
