I’m not trying to have this person lose their job but my experience was bad from arrival. I brought a long time friend out to eat and we were craving breakfast food so why not denny’s? We were seated fast and given water but somehow there was attitude with every jester. I didn’t think much of it but felt discomfort with every moment the waitress was around. While discussing what we wanted to order she quickly comes to the table speaking abruptly and loudly interrupting us which is fine because i know she has multiple people to attend to but upon saying no she just scoffs and once more there’s this unwavering attitude. We notice the tables around us just staring not knowing who’s to blame for the passive aggression. Respectfully, in hushed tones I mention to my friend that I feel this tenseness. My friend has a deep sigh of relief as they too were having the same feeling. I understand having a bad day but to my chagrin she was very friendly to every other table with warm squinting eyes and friendly conversation. She asked for refills and had fun banter while doing it. As a seasoned worker (long tenure) I would expect her to give every customer the same kindness because you never know who’s going to tip better than the next and who’s day your making. She never came to the table to ask for refills. She never made small talk. Every time she made an interaction her eyes widened as if to size us up and wasn’t that warm squint i noticed from her assisting all the other customers. I felt so uncomfortable at one point I put my wallet on the table because I felt like she was judging us based on her own prejudices. I don’t know if that’s actually why, all I can say is it didn’t feel right. I felt like i had something to prove so I tipped half the bill. I don’t know why, the service was awful but we’re all here struggling so remember tip your waiters just don’t award negativity just the normal amount you have nothing to prove!
