We don't have a fixed day to do somethingthing, but my nephew and I do weekly order something from the grillroom closeby. Not all staff but most know when I start with the order what the rest is and complete it for me with adress and phone details.
As students a couple of us went to a steakhouse once a month, we threw all our small change in a bottle took it out the last friday of the month counted it and saw what we could get for 5 people for the money. We mostly went to the same place and we sometimes ended up eating fries and mushrooms or sharing the daily menu between the 5 of us and we paid with the small change which we put in small heaps on the table after the meal. Just thought of this, thanks for jogging my memory those were fun times. And as I was the only one with a car back then we all pilled into my poor mini cooper.
