what part of “we’re closed” is so hard to understand?

i was standing at the door waiting to lock it behind the last customers we had (shopped up until the last minute and had a bunch of breakable things they wanted wrapped, mind you!!) and an older man and what i assume was his granddaughter walk up trying to come in. “oh, sorry we’re closed!” i tell them. “oh, you’re closed? what kind of things do you guys sell here, can you give me an idea?” i rattle off some of the main categories of things, including furniture. “oh, furniture too?” “yep” “i want to just come in and look, i don’t want to buy anything. can i come in and look?” “no, we’re closed.”

my store doesn’t sell any essentials- NOTHING that someone can’t wait until the next day to buy. it’s so so frustrating that we have to keep the doors open until the minute we close- and customers will come in right up until that minute, and even try to after that. since we’re closing down in a couple months anyway, i really want to just start telling people that our registers are closed and they need to come back tomorrow when we’re open. it’s so disrespectful and gross that people think we’ll be serving them with a smile, when we still have a ton of closing duties to do and i just want to go HOME. it’s been nonstop busy since we’ve announced closing, and i’m already so sick of it.
