I have worked out why they only gave me 8 Wicked Wings instead of 10.
Whoever picked the order used the wrong size box - it was too small. So only 8 fit in it. But instead of transferring them to a bigger box and adding the other two this bitch just said "fuck it" and sealed it up with eight in it.
It wasn't a mistake. It was a malicious act. I should have complained.
I will mourn those two lost wicked wings for some time longer.
