I agree having the knowledge of What you ordered Who is is coming from AND based on tracking info approx date of delivery.

How can you not know what you purchased??

Having many decades behind the counter and svc dept at motorcycle dealers and small shops. The customer who comes in and wants us to find the part for his mc is ridiculous .
One of the classics is this.

How you doing finding everything ok?
Um yeah i need a part for my dirt bike'
Ok what are you riding / working on?
Red honda
Great what year and model?
Its a red honda!
I understand do you know the year?

IT'S A RED HONDA WHAT ELSE DO YOU NEED.

Here take a look and tell me which red honda you have. Turning one of the parts books over to him.

YOU'RE AN IDIOT HOW CAN YOU NOT KNOW WHAT I NEED???

End of interaction.

The guy who pulled a knife, on my co-worker, because he was pissed [ in general] ended up much better
