Sitting in the diner at the beginning...

First of all, I love the movie, but...

These dickheads are all sitting at a diner dressed exactly the same way when they pulled off the heist and they wouldn't expect that this might come back on them? Even if you pull off the heist, this is the stupidest way to get identified after the heist. I get this isn't the way the movie went, but if they even pulled it off perfectly, this is really stupid!

Suspension of disbelief is a great thing but this is a glaring mistake in script writing... or just to show how dumb these criminals are, possibly?
