Like to add something, normally at my only local one, they usually don't accept the coupons but willing to knock off $2-$3 bucks for whatever the sandwich is.
These coupons hurt the little shops and I'm thinking that's why the other one closed as well, plus having a horrible location.
I find that the more they toast it, we always tell them to go through again if it's not too busy, the better it tastes... seems like the bread isn't cooked all the way through, and tastes infinately better half burnt.
Plus, also depends on which place one goes to, we get perfect ones from the local one, but we go to the mall's shoppe run by foreigners, and it's horrid mess that just makes for a lousy dine out.
