Ah, the invisible woman customer trick! Notice that the guy helping the guy didn't bother to say "someone will be right over to help you!" He was too busy helping the probably uber-fit athletic dude. That's poor customer service, I'm just saying.
Personally I get annoyed by the over eager must jump on customer as soon as they open the door kind of thing...... I want to be left alone until I approach them with a question.... One person's poor customer service is another's personal space...
