Tbf, Waitrose is generally over-priced and you can get pretty decent quality at LIDL.I agree; I wasn’t happy with that bit :
should have been “ would prefer to shop at Lidl but realises he can’t avoid shopping at “ overpriced” Waitrose and so goes for the reduced items because they represent a bargain “ . ( Even if they go off in a day or two ; and thus actually end up being more expensive , in terms of what you get for your outlay ) .
However, perhaps the analogy could be modified by having a list to take to LIDL and then Waitrose, but the shops are shutting, so just fills the trolley with anything from wherever he is so the cupboard isn’t bare? Sometimes it’s Waitrose, sometimes LIDL, sometimes B&Q.
Oh - and the list is generally out of date or has a bit missing as the person looking in the cupboard before going shopping is a f***ing idiot.
