They do near me as well. But doesn't mean you have to both go in. They are two adults with no kids, there's no reason they both have to go into the shop. Her reason is just that she wants to.I am not defending Brogan whatsoever but I live in her area and most shops do allow more than 1 person into the shop - I I don't think there's actually an official rule on it.
Still obviously agree that it was a non essential trip to home bargains and she's and absolute moron to advertise that she went to buy unnecessary tat.
