I went to starbucks and told them my name is penis
Why would you do such a thing?
I thought it would be funny for them to call out my name
I'm sure they were really thrilled with you. It's wrong to use obscene words and mention your private parts in public. They'll kick you out next time.
I will still go there and order a drink from them.
It's wrong to force people to say such words like penis. It's not really nice. You should not have fun at others expense.
