This specifically happened to me in the Umi on Dame Street. The staff mixed up my order with another customers. The food had only just been set down by a waitress who left to drop food she had to other tables. Then straight away before...I even noticed the food was wrong another waitress came with my order and gave out to me for not immediately telling them of the mistake. As a customer I would have been fine with the mix-up as I have worked as a server before and know how stressful it can be when busy. But for waitress to blame customers for their own mistakes is extremely unprofessional. I didn’t say anything, paid for my food and left, but you can be sure that myself and the friends who recommended this place to me (who were regulars) will never be going to Umi again. The food I would rate a solid 3.5 out of 5, so you can easily find somewhere just as good, but with better service.More
