We had made a reservation at a restaurant for 7pm. We arrived on time to find a line of customers waiting to be seated. I approached the head of the line next to the cash register and asked the first party waiting to be seated if they had reservations. They said they didn't. I then turned toward the dining area waiting for assistance. As a waitress approached, I said to her that we had a reservation for 7pm. She acknowledged our reservation and said our table was ready, and motioned for me to follow her to the table.
The first party then began shouting at me that I was butting into the line and should go back to the beginning of the line. I was nonplussed, but refused to go to the back of the line. The two-person party continued to made a scene, hollering at me. I motioned to my party that our table was ready and we were then seated by the waitress. In doing so I asked another party waiting in line if I did something wrong. I was told I should have waited for the first party in line to be seated.
Did I act appropriately?
