I am on res 5 level 9..I think its level 9,its the level where the minute you seat them they want to order right off and eat and are done before you get done serving the others..I am stuck here I can not get past this level and have tried everything..I can make it 19,250 and thats it

how many tables should I serve?? I have tried serving any where from 2-6 tables..Should I go for more?
