Comcast>TD Bank?

If you've never gone to Comcast to trade in a broken modem or cable box then you won't really know what I'm talking about, but I'll try to help you understand. I was waiting to deposit my Christmas money yesterday and started thinking about how easy it would be to jump over the counter and grab whatever I wanted. This shit doesn't fly at Comcast. They have like 4 inches of bullet-proof glass between you and the lady behind the counter. Also, when you trade in whatever malfunctioning piece of equipment you have, you have to put it through a box that they open from the other side when your side shuts. Really? Because of all this, you have to talk to them through the weird microphone things like at the movies that you can't understand (speaking of which, why are they under so much protection?). It just seems over the top to have a bank have wide open access to reach across the counter to an area holding tens-of-thousands-of-dollars, but yet Comcast protects their employees like they're selling Kryptonite.
