Okay, so i was at this restaurant and i worked out a deal to get them into the computer age. i wrote some invoicing and order system for them to make pies productively and have orders placed online. i worked out something with them in an under the table type deal where i got some money up front and mid way through they decide they dont want it anymore. so i told them to go fuck themselves and i am just going to sell it to someone else. anyone have any advice on doing these types of projects?
