Primark has launched a new line of Friends clothing commemorating the 25th anniversary of the US TV comedy show.
But a "ridiculous" error in one of the T-shirt designs has left one shopper feeling a bit embarrased.
Friends fan Dan Molloy picked up a unisex T-shirt, celebrating the programme's anniversary, when he spotted it for sale in Primark.
However, it was only after he wore it that he noticed a typo that had slipped past store employees.
The company had accidentally misspelled the word 'watching' in the design, leaving out the letter 'i'.
Dan, unimpressed, informed Primark that it the T-shirt he had bought was missing a rather important letter.
He tweeted to Primark: "I got this top from you and have now noticed the typo in it. How ridiculous that noone (including me) noticed it and it was allowed to be displayed and sold. I no longer have my receipt, what can I do? Thank you"
Primark said it was happy to refund or exchange the item - with or without a receipt.
They tweeted in reply: "Hi Dan, we are sorry to see that, you are of course welcome to return your T-shirt to your local store at your convenience for a full refund or exchange. Thanks!"
The glaring error is not the first to appear in recent weeks.
In early September, an eagle-eyed shopper noticed a Christmas bauble sold at Primark accidentally misspelled the festive season.
The Disney-themed product read "Baby's first Chirstmas", much to the amusement of shoppers.
