<human>: Summarize the given text in a few sentences.

Hey guys, I'm 16 years old and I work as a server for a Japanese restaurant. Recently my coworkers have been making a decent amount more than me. I almost always get 20% tips, but my coworkers often make more than me. Often times it's usually luck. I get the table of 3-4 and they end up getting the reservation of 20. All my manager sees is numbers. I topped the charts for tips for almost 3 months and only in the past 2 weeks have I been near the bottom. Due to this I've been getting less and less days to work and it's really scaring me whether or not I'll be fired. I'm the only guy server and she said she prefers girl servers and I'm also 16 years old which makes it difficult for her CPA since I "serve" alcohol. My Co workers know I'm an extremely hard worker and one of them texted me asking why I'm only working 2 days this week.
<bot>: I'm the only guy server. I'm under aged and I've been under-performing recently and I'm scared about losing my job or getting cut to an amount of hours that isn't even worth working.
