Each game round has their own weird little strategy that we all have to figure out, however, with 5.9, the best way to reach goal is to seat everyone according to color filling all seats (except the last green seat, because you should save that for guitar girl) chain everything, including shoes, questions marks, and so on.In this round there are 6 guitar girls that will show up throughout this level, she comes in these colors in this order:Green, Beige, Brown, Green, Brown, Beige...so everytime you clear a set of customers, keep one of those seats available for her and for the heiress, she shows up only twice, in beige first, then in blue.
At the top of the game, I waited for the waiting benches to load completely up, hit the radio when it glowed, then seated everyone quickly, handed out their catalogs, then grabbed the gentleman and gave him his catalog.Waited for all the questions and shoes and purse orders first, THEN took the orders.If you can keep on top of the champagne, hit the businessman and movie star with champagne BEFORE they decide what suit or dress they want or after you've taken all the orders up to the seamstress.The chain will be broken if you try to give them champagne when their clothing choice is shown...
Good luck and I hope this helps.

If you do the above, I can pretty much guarantee that you'll make goal, if you refine this, and pay attention to how you move and chain things, you've got a really good chance of making expert.

As a person who flies internationally at least once a year, no, I would not get on an angry looking plane...it's bad enough with other people's tempers (including my own.)I need the plane to at least not look angry!
