I think a neg coming-

I posted an item yesterday, the day it was bought and paid for. I received an email from the buyer today asking can I leave feedback. I said my feedback is given automatically once feedback is left, that way I know you have received your item.   Right or wrong thats the way I do it.

 

I just got another email saying "ok **bleep** head - I'd better receive it"

 

If I do receive a neg would I have grounds to have it removed?
