Usually people like that will reciprocate and take you out when you travel to where they live, but if you're too poor to entertain out of town friends in sales tax free Portland, I'm guessing you're also too poor to travel to where these friends live. Assuming they are actually friends. Frankly, you sound really angry and not a lot of fun to be around.
