Ordered a pizza at 3.30 last night as was peckish and couldn't sleep. Was paying by cash. I was the only one in the house at the time (I'm pretty small and young-looking, mid 20s).
Anyway, the delivery guy pulls up and I run out with the cash to greet him before he rings door bell to stop him waking neighbours. He seems like a nice enough guy etc, but physically very solidly built, tall, big. He asks to step inside so he can read the bill in the light. He's literally towering over me blocking the door-frame.
All was fine and I paid but for a moment I got extremely paranoid that it was very easy for something to have happened, if he wasn't that nice. I had literally just brought a random stranger into the house.
Aibu to think he could have made a note of the bill amount in the car so I could have paid him asap rather than fumbling with the receipt.
