Denny's review: food/ shift manager

At 6:00 am /12-27-2019 A coworker and I stopped at #8174 for breakfast. The poor waitress was overwhelmed by all the customers. She was alone with one cook. As I noticed she was leaving I called her over and gave her a cash tip. The man who took over her tables had just came in to work. When our food was served it was cold and he was not interested in the bugs in the food. I still paid the bill 32.93 for two. When I paid the bill I left no tip because I had given the girl 6.00 before she left. This upset the man who started making racial slurs. When I asked for his name he refused to give it to me and said call back at 7:00 to talk to a Manager. I was outraged and left. Cold food, bad service, and racial slurs . I took the morning off to solve this issue . Someone please contact me to give me status on this issue.
