Go Stand On The Beach And Wait

I run a small shop online for items that I make by hand. At least once every single week, I get messages from customers who think that the US is the only country in the world, even though I clearly state that orders are being shipped from the UK. They always say something along the lines of:

Client: “It’s been five days, where’s my order?”

Needless to say, I have lost my patience several times now and “jokingly” asked if I should fling their package across the ocean.
