Dollar General review: Unethical Behavior

I went to the Dollar General store in Wayland NY on Saturday December 5 2020 approx 1:30 pm to purchase a propane tank for exchange and the store clerk told me there wasn't any full tanks even though there were clearly several tanks with a blue seal on them The blue seal means they're full and haven't been used yet. I told her there were tanks with blue seals but she stated they were empty. Even with the blue seal on them! She said they had been tested by the store and found to be empty. This is fraudulent. Plain and simple she lied. Why? I don't know there were only two left maybe she was saving them for someone she knows. But she was lying and I know it! I will not shop at that store anymore! Nor will I shop at any Dollar General store because I find that your stores have a multitude of unethical behavior issues and I am sick and tired of being tricked and lied to! I don't want any response from you people, I don't want anything, ever, from you people. Just know your customers are not dummies and we know when we are being lied to! I have to sign in to send a complaint! Are you kidding me! Last straw!
