This game is awsome, beat it without fail or restart after level 2. lt gets pretty easy once you know what you are doing, the tip on lvl 3 is the key.
For those who skipped it, the costomers wont enter the same store of the same level more than once.
Also newstands and icecream's primary job is to lag the costomers... not to make money...
