Out to lunch?

Ted and I went out to lunch today at one of our favorite restaurants.  The young woman who has been working as the cashier waited on us, so I asked if she has changed positions.  She said she has, and told us this is her third week waiting tables.  It’s her first week doing it on her own and the reason we haven’t previously seen her as a server, she said, is because she only works on Tuesdays.

Today is Monday.
