Today, I used the last of 3 Groupons (I had to buy 3 for this offer) at Burrito Gordito. The burritos are quite good and large and thus filling. But during 2 of my 3 visits, the cashier (perhaps likely the owner) tried to short change me by giving me less change than I should have received, and today telling me my Groupon was worth less than the offer and that it was expired. Both were wrong and lies. Unfortunately, I find that many times when you use a Groupon, shop owners try to make back the discount they've given by shortchanging you or ripping you off somehow. I will no longer eat at Burrito Gordito!
