To Puffi, thank you so much for loading my last crate of 4 cheese, you're awesome!
Jellsio and ea_sweetface thanks for your advice. Jellsio advice to open mine and buy 5 shelters at least to make it worthed ( for this I have to save coins about 79,000 coins) and sweetface suggested that I sell goodies, esp. Something using sugar, like cakes, ice cream, etc with max price at my roadside stall to gain a lot of coins and ignore small truck orders (coffee kiosk is the worst machine acc to sweetface, cause sucks a lot of sugars, hahaha.... Thanks a lot guys for the input, I will work harder now to produce good stuffs to sell ...please come by once awhile check my stuffs ... Help me build my farm. Thanks again, you are all awesome!
