The company asked its online followers to "finish the sentence: 'I shop at Waitrose because...' #WaitroseReasons".
Many users replied with comical answers, mocking the store's upmarket reputation. They included:
"I shop at Waitrose because it makes me feel important and I absolutely detest being surrounded by poor people."
"I shop at Waitrose because Clarrisa's pony just WILL NOT eat ASDA Value straw."
"I shop at Waitrose because darling, Harrods is just too much of a trek mid-week."
"I shop at Waitrose because the toilet paper is made from 24ct gold thread. (Unless it's the Essentials range.)"
"I shop at Waitrose because I want to prove to Jeremy Kyle that I am not a 21-year-old dole scrounging father-of-two."
Waitrose took the tweets in good humour, later writing: "Thanks again for all the #waitrosereasons tweets. We really did enjoy the genuine and funny replies. Thanks for making us smile."
