this has become a hobby of mine , dining + gaining work at the same time -just thought id share . every town usually has a community cafe and these are great places to eat lunch cheaply . the banter is usually good. get chattin to the volunteers/servers and they will likely let you put up a poster / flier on the wall . i park my van right outside each time and within a short time ,after a few short weeks , you will be seeked out for quotes as you dine. you gain a certain trust, street cred ,trust worth having . give it a try !
