Reasons Part 1

So I've been working at the bank for about 2 months now. I'm still not fully familiar with the system. I'm about 95% there. Mondays and Tuesdays are the busiest days so all four tellers are working. The other days there are usually 3 tellers working and Saturdays only 2. Also, at our bank, there's no number or ticket system. There aren't poles with velvet ropes that create a line and there are no signs that light up above the teller's booth to notify the customers that they may come. We just say, "다음 분 오세요." (I kind of feel like I made it out to sound like it's a ghetto looking place but it's actually quite nice inside.) When it gets busy, people are very civil and form their own line. But since the day I started, I noticed something. When it's not busy and there's one customer that comes into the bank and they have a choice of which teller to go to; 95% of the time they never choose me.

Here are my reasons why:
1. I'm the new guy.
2. I'm a guy.
3. They're racist.

Let me elaborate on these reasons.
The first reason, I don't blame them. I mean even I would prefer to go to the familiar face. Also, because I'm the new guy, they feel maybe I'll be a little slower or I'll even make a mistake. Understandable, especially because Koreans are so impatient and hot-tempered. But a few more months of this and that reason is out the window.
The second reason, I'm not so cool with. There are a lot of 아저씨 customers. Therefore their hormones lead them to the other 3 female tellers. Understandable but still...c'mon.
The third reason is more of a hunch. Basically...I'm pretty dark for a Korean. That's it. I guess racist is kind of harsh haha.
