Took my daughter and 4 1/2 year old Grandson to Red Robin last night. Arrived around 4:45 and were seated. Not many customers at the time. Sat waiting 15 minutes for a server to bring us menus. There were 5 or 6 servers standing around chatting with each other. Finally got up and left. Always wondered what it would be like to be invisible. Guess I know now. Won't be back!
