The Food and Margaritas was overall 5 stars , our server was very sweet an informative. My reason for the 2 stars is the way the night manager John treated us finally. My Fiancé and I are both foodies. My Fiancé and his niece whom we came to Ahmerst MA to visit, both suggest to go have dinner there. My Fiancé grew up in this great small town, we both live in Chelsea Manhattan NY NY current. When we tried paying for the check the waitress returned to table and told us they no longer accept AMEX. No where in entrance of the restaurant does it say that they dont. Very nicely my Fiancé explained that they should be clear and should have a sign of some sort to explain so. We had collectively 3 Amex with us. Living in the city we dont come across a problem like this. She suggested that we can leave an ID or Driver's License so that we may return and pay effective. I did as she suggested and left drivers license with her , so they dont assume that we were trying to dine and ditch, smh. I asked for the MOD to come to table so we could explain what's going on. He instantly profiled us. My Fiancé took charge of conversation with John. He walk up before we said anything and said "ive been working here since restaurant open and we have never charges AMEX card." My fiance found it weird because when attempting with the waitress an American Express icon/logo appeared on register screen, in which he insisted that there wasnt such thing. My Fiancé then walk with store manager up to register where the Manager had to find himself explaining the logo/icon option for American express on the register that he so call "never seen in the 5 yrs his been employed there!" During his conversation with my fiance he told,him that none of the small business in town accept this Card due to a 5% interest charge that the company doesn't want to pay. He then tell my Fiancé that he should come to the "Valley" more often and he would know that all the places in town don't accept this card either. When in Fact the Pizza restaurant next door does!!!!! Also, my Fiancé grew up in the "VALLEY" thats an insult. And to wrap the conversation he tell my man that he "Would love to talk about this all day,but he has customers to take care of." No apologies none. The check will be taken care of, and in fact I'm not embarrassed at all despite the waitress telling all the staff. But he instead of profiling and making snark and offensive remarks should of handle things in a more professional manner. I will call in morning and speak with the Store manager in charge further. Disappointed in his POOR customer service. Will be returning food was great. Sucks about the Night Manager shame he's so ignorant.
