Bad Service - come again

There is a great cafe up the road from where I live. We go there pretty much every weekend. The thing that gives me the poops is that they can have 6 staff waiting on the tables, but you still need to wait 15mins to get a menu ad then practically trip someone over to get your order taken.

Crazy thing is that the food and coffee is so good we keep going back. What I don't understand is how there can be so many staff and still no one seems to serve you. It seems that we become invisible. I have had fantasies about going in with an airhorn to see if that would get us served any quicker. I always think when I am sitting there waiting that I should kick up a fuss. But I never quite get the guts to do it. Maybe next week....
