Nothing rude about it, it's the way I prefer burgers. I've never considered restaurant burger special or 'pop'ish, mostly just convenient. I do put lots of raw onions on the burger though, the refreshing crunch of freshly sliced onion goes well with the greasy meat. Restaurant burgers rarely have much onion, and when they do it's usually cooked or limp and sad. A lot of restaurant burgers go heavy on lettuce instead, but lettuce is bland compared to onions.
