May be you can hack your way into talking to customers. You don't have to think of restaurant workers as people you are trying to sell to understand their pain points. This is one thing I have tried myself. When you go to a restaurant next time try to have a casual conversation with one of the workers. Try to get them talk about their pain points without directly asking them. In most cases they'd be happy to talk to you because you have leverage over them because you being their customer. And once you have understood some point points and developed a solution for them try to generate some demand for your product. You can go to one restaurant and tell them such and such restaurant is using this product and is doing great with it. And then go to another restaurant and tell them there is another restaurant using your product and killing with it. Also, read "The Paypal Wars." This book has a wealth of sales tactics you can use.
