When a wedding guest gave the bride and groom a £100 gift, she thought it would be gratefully received.
So she was understandably appalled to receive an email from the bride - a former colleague - suggesting she "adjust" the size of her cheque.
And, when she turned to internet forum Mumsnet for advice on how to respond, she was inundated with more than 1,000 replies from aghast users.
The bride and groom had requested cash gifts and she sent them a £100 cheque, which she considered "pretty decent", the woman said.
The couple duly emailed her after their honeymoon, saying how pleased they had been to see everyone.
