Why is my Baemin order being rejected?

This is ridiculous.
I didn't even write any special requests,
and since the amount wasn't large, I thought that might be it,
but it's not even a busy time, so getting rejected
really hurts my feelings.
If they're going to reject orders, they should just close the shop on Baemin.
I don't know what they're thinking.
I was so angry I considered calling them,
but I held back.
