<human>: I am a server at a restaurant. 

It's awful for a lot of reasons.

That aside, serving makes a decent amount of money and when I serve 5-ish days a week that covers my entire apartment's rent and my wife's salary covers the rest of our expenses with enough left over to put money into savings each month.

The problem is that I keep getting scheduled for takeout shifts 1-2 days a week, which results in me losing $50-100/week that I would make serving. 

I've asked him if I could not be scheduled at takeout but he says it's "just the luck of the draw" and I'll need to help out "until they hire more takeout people." Thing is, they aren't hiring more takeout people. They hired two new servers in the last month alone. 

Another issue here is that there are several other servers with the ability (i.e. training) to work takeout, but it's only myself and maybe two other servers who are assigned takeout shifts while these four other servers are never scheduled takeout shifts. 

Now, on to what I need help with.

Two other people have complained to him (about the same issue but also another position), but haven't done it tactfully and one even yelled and cursed. 

My question is this: how can I approach the issue with him without him cutting me off immediately, and how do I humbly ask that those other four servers be included in the takeout rotation?

Give me the gist of the text in a nutshell
<bot>: manager scheduling me below the station I've worked a long time for and not doing the same for other servers. How do I approach him about it?
