Just nearly punched a Tesco self checkout machine

I have nearly 20 quid in vouchers. Open the app to put them into the checkout.... This fucking thing appears.

Now.

I wouldn't normally be so pissed off......
But I had, not 20 minutes prior, been logged into same app making up a fucking shopping list.
I had also logged into the website twice.

So why

On god's green fucking earth..... Does it log me out RIGHT AT THE FUCKING CHECKOUT?!?!
AND THEN TELL ME THAT "due to our ongoing security blahblahblah, /you/ have to reset your password!"

.... Could you not have done that.... AT ANY OTHER FUCKING POINT BEFORE THAT!?!?!

*SEETHE*

Then the card machine had the affront to demand my pin.

Cherry on fucking top while I'm having a fucking meltdown

No. I am not doing well right now. This is the first time in days I've managed to leave the house under my own fucking steam.
