A wedding gift can be an expensive purchase, but what if you didn't give a large enough gift?

That's the question that's facing one person who posted her conundrum online.

A guest of a recent wedding went to an online forum to express her displeasure concerning an email she received from a bride.

The post stated that the writer was an ex-colleague of the bride. She gave the now-married couple a check for 100 pounds or about $144, The Guardian reported.

But that may not have been enough for the couple.

The guest claims she got an email that said, "We were surprised that your contribution didn't seem to match the warmth of your good wishes on our big day. In view of your own position, if you wanted to send any adjustment it would be thankfully received."

The gift giver took to the Internet and asked total strangers what she should do, reply to the email, call them or ignore it.

Many said she should have canceled the check, while others were a little more vindictive, saying she should tell mutual friends, going so far as to blind copy them on the email gift request.
