Asking too much, disrespect, or am I crazy

Soo.. hear me out. After starting out as a bartender and working my way up, I (25M) just became interim manager at the job I’ve been at (1yr) since they’ve opened in Houston. The owners decided barback and busser positions were not necessary as well as hosts only needed on the weekends. Hosts thing I understand because we’re busiest Friday-Sunday, but everything else is kinda meh considering here we are on this topic now. The goal is simply to keep that part of tipped out money in the servers pockets as well as get them more involved with each other as a team and helping each other out in general, but this means they have to of course pick up the slack of those positions not being around. It is successful to an extent. Everyone helps out for the most part, but the moment they feel they are a tad too busy with tables they don’t help in any area other than bussing their tables. Don’t get me wrong it’s much appreciated, but when it travels over to when you no longer are busy and still don’t want to essentially rest the restaurant for more guests and to make more money it’s kind of like wtf. Yes ik manager and all that good stuff only thing is when there’s no traction application wise there’s not much wiggle room.
