People cutting lines in stores to "ask a question".

There seems to be this trend going on where people are walking to the front of a long line to "ask a question", then getting serviced before everyone else.

I was next in line to make a purchase at H&M the other day. I begin to walk up to the counter and some random guy with a bunch of clothes in his hand walks in front of me telling me "sorry sir, sorry sir. I just need to ask her (the cashier) a quick question". I nod okay. He asks her if this shirt is on sale. The cashier says "yes, it is". This guy then proceeds to put his clothes on the counter to pay for his stuff.

I'm like "whoa... What are you doing? The line is back there". I point to a line of 6-8 people patiently waiting. He's like "don't worry my friend... It won't take long". I don't mess around in situations like this and shifted my way in front of him at the counter and told the cashier to ignore him and to process my stuff. His entitled ass is looking at me like I'm the asshole in this situation. He could have easily asked an associate who was working on the floor to price check the article of clothing, but he decides to pull a fast one on everyone.

Over the past few months I've seen this crap happen at other retail stores, banks and grocery stores. It's annoying that people think that their time is more valuable than others.
