I have been writing checks for 25 years and never had a bounced check or any other problems. Today I wrote a check at Walmart, which I have done probably hundreds of times before, and my check was denied. I totally humilitated in front of a long line of customers and my own mother. The cashier gave me a little slip of paper with a 1 800# on it which I called as soon as I got home. I was told that the reason I was denied was because I had written several checks in the last few days. So what? What business of that is theirs if I have the funds to cover my purchases? I thought that was the purpose of scanning the checks in the first place- to make sure you had the funds to cover it. Now I am paranoid about writing a check anywhere!
