I'm going to work a part-time job as a security guard lolololol

‌Since I've been going to see a lot of baseball games lately, I needed some quick cash, so I asked an older brother I know who is a security supervisor for a part-time job.
He hooked me up with a one-day substitute shift as an apartment security guard hahaha
At first, he told me to do a 24-hour shift, but I told him I couldn't do it because I felt like I'd die working 24 hours straight.
So we agreed that a college student would cover the daytime shifts,
and I would only work the night shift hahaha
It's a 12-hour night shift with a 3-hour break, and he said he'd pay me 120,000 KRW hahaha
With this amount, it should be a decent help for going to the baseball stadium?? hahaha
Since I used to be a security officer in my younger days, they say the security company has high expectations.
I'm going to go and show off the majesty of a security officer, the ultimate master of service hahaha
But apartment security guards don't wear suits, right???
I've only ever worn suits in my entire life, so I'm a bit worried they might give me a security uniform and a security cap.
I really don't want to wear a security uniform... sigh
If all else fails, I'll have to try asking politely, saying, "I would like to work wearing a suit."..
Because a former security officer can't be seen wearing a security uniform...
