Social media, and Twitter in particular, can be very useful for answering age-old or controversial questions (was that dress blue, was it gold? PLEASE NEVER ASK ME AGAIN).

So when Emily Cousins asked this simple question, she expected a simple answer:

Which is better @AldiUK or @LidlUK ? #questiontime

Rather than getting a few answers of one or other, Emily got a reply from Aldi, clarifying that it was in fact them:

It's us. pic.twitter.com/DGdPlpzXDB

And then Emily got a whole lot more than she bargained for, as a beautifully British Twitter war began to unfold:

Sorry to break it to you... pic.twitter.com/2wEBraqGuq

We (respectfully) disagree.... pic.twitter.com/PKrelYdFpe

We have no other choice... pic.twitter.com/95bTFLENFI

You got nothing on us... pic.twitter.com/5DmEFEDNlp

Are you sure you can handle these moves... pic.twitter.com/JxmtC1lECg

— Lidl UK (@LidlUK) August 3, 2017

We invented those moves... pic.twitter.com/TrnEjeel5K

Twitter, clearly enjoying the feud unfold, then began to coax other supermarkets, which lead to even more hilarity:

You don't see these kind of bants from @waitrose or @marksandspencer pic.twitter.com/ydcDUNVEP1

We're late to the game tonight but we've saved the best 'til last .... chin chin pic.twitter.com/RKaiZwh3lg

Waitrose thought it had won the last word, until M&S dealt this savage blow:

When it takes 4 hours to think of 'that' reply 😉 pic.twitter.com/sNOaxd3pzB

And meanwhile, Aldi and Lidl continued to go at it:

What time do you call this... pic.twitter.com/jB34IrQ6YI

— Aldi Stores UK (@AldiUK) August 4, 2017

Lets do this thing. pic.twitter.com/k90muQlxNN

Hurry up and get your 8oz gloves on. pic.twitter.com/nIGCMfIAbT

— Lidl UK (@LidlUK) August 3, 2017

And whilst the fight seemed to reach it's pinnacle, the two supermarkets decided it was time to call it quits:

Maybe it's time for us to kiss and make up? pic.twitter.com/M6blPsNgwk

Seems like Aldi and Lidl have it all, cheap alcohol, low prices and top quality banter.
