Both the statements of Bi and Nine and of Johan are totally true, and I agree with Telstra (

) to some point: quality service is just like quality products in general, you just don't get it anywhere and you are plain delusional if you expect so. You can get good and bad service irrespective of the price and depending only on the place.
In Barcelona you can have a coffee for like $1 to $1.5 and it basically will vary according to the location of the place (that is, more or less affluent, tourist-oriented or business district neighborhood) and to whether you take it in or out in the terrace, but it will have NOTHING to do with the product or the service. You can't expect a better coffee and service if you pay more or if it is in a posh neighborhood, and even less if you are not a regular.
There may be particular places where you can find a quality product and service for the same price you would pay anywhere else, but it would cost you time, which is ultimately money, to find such places, so if you want to be served excellently
by default, you just go to the Palace Hotel and you will be charged $8, but it would be excellent coffee, excellent professional service and they will include a few tasty cookies
I honestly don't expect, WON'T expect much from people who are just earning a living. It always seemed to me a pretty spoilt, conceited, miserable, ridiculous attitude to expect to be waited on hand and food for a couple miserable coins because you take yourself for Mr. Client as if you were Mr. Marquis of High-Maintenance, like my father used to do. When I want to be comfortable I'm at home or with friends *ahem*, not with someone who just needs the money. It's funny how the prejudice people usually have about whores as not being capable of delivering a "good service" because they are just interested in the money, it's precisely the rule in just any other "decent", "professional" job.
