Few people give a toss about Tesco losing money, or even going to the wall.
It’s the way attention is now being drawn to their regular dark-art style practices of skullduggery that is worrying OTHER retail outlets - because, of course, they’re ALL at it in some shape or form.
If they were not, then there would by now be a shining star out there recruiting all the cream drivers on actual full time contracts that pays similar rates to agencies on tankers. - ie £50k for 4 on 4 off 11 hour shifts.
Wot skullduggery? I hear you cry…
Getting supplier farmers to pay bribes - so their produce is not refused.
This, on it’s own is a very serious matter indeed. Perhaps someone has cocked up the accounts, by accidently including the amounts paid in such bribes into the “full gross operating profits”, when traditionally, it would be black market money, kept under the counter, and strictly off-book.
It’s not the money that’s causing the trouble - It’s the soft underbelly of supermarket cartel standard practices thus revealed! 
Did Warren Buffet lose a Giant’s squirts-worth of money? - Yes.
Will anyone at any supermarket go to jail? - No.
Will any shareholders lose out? - They already have, are, and will continue to do so.
Will any Tesco’s drivers lose out? - Who still doffs the T shirt, rather than works via a contractor/agency? “What could be lost, has already been lost” I’d argue.
Will any customers lose out? - I’d argue in Tesco’s case, the ones who’ve already decided “not to shop there” lose more than those who’ll not be put off spending their numerous vouchers, that ■■■■ all over other supermarkets for sheer amount of them. 
Makes me sound like a Tesco’s firms boy don’t it? - Well, much as I’d like a real and proper job - I’ll never likely get past the “bouncers” that are Wincantons, TRG, and now soon to be Stobarts…
