Waterstones invited customers to a 'willy' rendezvous instore.
Willygate
The rude gaff was made on Twitter at 9.13am on Tuesday (21.06.16) when the book store in Uxbridge, London, warned its book-lovers to ignore the rain, dress for the occasion and visit the store.
The tweet read: ''Morny! It's raining and rubbish outside... but warm?! Anyway. We're open until 7pm tonight. Put your willies on and pop in for a browse! (sic)''
But it wasn't long before eagle-eyed customers spotted the hilarious spelling error on the social media account.
The tweet had accidentally muddled up ''willies'' for ''wellies'' - changing the entire meaning of the invitation.
It wasn't long before the tweet was quickly removed and another was posted acknowledging the error, which read: ''Erm... oops... obviously, put your WELLIES on if it's raining. I'm going to go and hide in a corner now (sic)''.''
And this was followed by another that read: ''It's Monday morning. I make no excuses #willygate (sic)''
