My first job was at a party place as host. I did everything and worked my butt off. Most the party captains like chuck e cheese make minimum wage. At the time I made $5.75. I depended on those tips and would have not stayed if I did not get them.
On avg I made $30-50 a party but like I said I worked my butt off. I wrote names down for presents, cut cake, served food etc... It is pretty much expected to tip.
We go to about 2-4 parties a month. Most kids now a days dont "work" the party and I see most parents tip them about $25
