What happens
You're threading extension cords under the poetry table, chairs half set up, when the front bell goes. It's tonight's visiting author, forty minutes early, tote bag and water bottle and an expression that expects the room to already be ready. Davion is at the register counting the float. Noreen is in the back on the phone with the caterer about a delivery that hasn't shown.
Whatever you say to her in that first minute, you still have twelve chairs, a mic check and a book table to finish alone. Asking her plainly what she needs gets you something specific and doable — a signing table, books stacked spine-out. Rushing the setup instead knocks over a stack of paperbacks and leaves you with a mess on top of the work.
By 6:15 the doors are technically open and a line of twenty or thirty people has already formed outside. Davion can't run the door and the register both. The author catches your eye and holds up a stack of her own books that isn't the one the shop ordered. Three things need you at once, and none of them are unreasonable.
The event happens. Whatever you chose, it happens imperfectly — people wait a beat too long at the door, or the register runs slow, or the wrong stack gets signed for ten minutes before someone catches it. By 7:35 the room is full and mostly working, and Noreen thanks you for holding it together while she's already counting the register in her head.
