2. no paper cups

Let's suppose the rush hour is after lunch, then everyone will be getting an espresso, someone macchiato (only tourists drink cappuccino after 11 am), but the price is the same. And basically you have a line at the bar and a line to pay. The bar can usually make up to 8 espresso at a time and people cram in front of it by the dozen and drink it in under a minute. You can pay before or after according to where the queue is shorter.
That sounds awesome. I can't even count the number of times I've waited for some goofball's complex six-word drink to be made so I can give the cashier $2 and get a cup in return. (Most places around here sell you the cup and you pour your own coffee from a vacuum pot.)
* I shit you not. It happened at a Starbucks in Wisconsin.
Bonus points if it's cheaper.
The customer insisted on the order as originally stated, and happily paid the extra two bucks for it.
Coffeehouses here in the States make things way too complicated but I guess they only continue to sell what the customers buy so it's our own fault.
I've got an Illy cafe machine at home :)
As far as pricing, I don't think you can make a living selling shots of espresso for $1, unless you sell an awful lot of shots or sell a lot of other things.
Saying "one espresso" is cheaper in Italy than the US doesn't really mean anything. Prices vary, cost of doing business varies, cost of living varies.
