Waitstaff

So I think I figured something out...well, in my own head at least. Here in Spain the waitstaff are not very quick, not very attentive, and altogether not the best I've seen. And luckily in Spain tipping is very minimal, just some cents, not 15-20% of the bill. I'm told that is because the restaurants actually pay their waitstaff good wages so they do not rely on tips. Pondering this I've come up with an explanation. They are generally good at taking your order and bringing things out relatively soon (although I have waited more than 10 minutes to get a glass of wine), but they do not check to see if you need anything else once they have delivered the meal. And heaven forbid you should want la cuenta, forget about it! But when they aren't relying on tips, there is no urgency to turn the tables over. It is easier for them to just have you sit there so they don't have to attend to the table anymore. Last night after eating dinner, I was trying to catch my waitress's eye to request the check and she walked by me at least 8 times without even glancing at me! When I finally flagged her down, it took another probably 3 minutes for the bill to arrive.
Guess I need to relax and not be so anxious to get up from the table...although if they would bring me another glass of wine it would be easier!
