Quiznos is where its at. Subway is good the odd time.
As for the conversation... I definitely agree that it is highly benefical for everyone to be able to post their experiences so that we are able to make better choices on who to deal with. I mean warranty issues are all ways a big topic and finding out who helps you out and honor them is huge when picking a vendor. Also, value when it comes to frags, variety and sizes are important when deciding who to deal with because, lets face it, frags are not cheap. This is particularly more important when dealing with online sources where you cannot actually see the end product you are receiving and the only way to know if it is worth while is by others comments and reviews.
Also, I think opinions can help stores a lot to work on their customer service and how they manage their companies. I used to go to Big Als here in Kitchener as little as possible because their fish were unhealthy a lot of time, coral tanks looked like crap and prices were out to lunch. Recently though, tanks have improved dramatically. The coral tanks actually look nice and have much better lighting. Prices can still be high on items sometimes but there's no real competition in the area to drive them down. Overall, a HUGE improvement that I am sure was customer and management driven.
These are where opinions matter for both the customers and vendors.
