My wife is the worst orderer/lack of hurry in a line and it drives me absolutely INSANE..................
we have gone to the same restaurant on Friday nights probably 3 out of 4 Friday nights (pandemic exception) for probably 6-7 years. the menu has changed very, very little. my wife orders one of 3 items every time.
yet... every. time. we wait 15-20 minutes for her to peruse the menu, shoo away the waiter/waitress, then finally pump fake making a decision... before making the server stand there another 3-4 minutes while she debates what she's going to get. "oh, i'll just go with the usual again....

"
busy place. lots of customers. thankfully we tip generously so they haven't thrown us out yet.
