Customer service is not the best at Best Buy in general. They never have enough people available on the floor to assist you, but this had to be the worst customer service I've EVER experienced in a Best Buy.
When I entered, no one greeted me hello and I actually saw the employee look over at me. (Mind you it's 7:30 on a thursday night - I swear I heard tumbleweed, that's how dead the store was. So it wasn't like they were swamped.) Then I had to search for someone to assist me. I found two guys talking in a corner. As I approached them, they continued their conversation for a while instead of immediately addressing me. Then they didn't say hello, they just stopped talking and looked at me. (Oh I'm sorry for disrupting you both, I just assumed you were both working and were able to provide me with some assistance.) I said hello and asked for what I was looking for. They acted like my request was unheard of (an external mic for a mac). One finally responded. He looked around with me for a bit, mumbling that they didn't have anything. Realizing he was inept, he referred me to another employee who actually was helpful (sorry I forgot your name- that extra star is for you!) I wound up not getting the product there because I saw it cheaper online while at the store.
