Sorry Hypnorm, I've only just seen this. I'm with you - I'd be outraged if someone said that to me!
I do our weekly shop at Aldi, and go to Tesco's or Asda once a month for stuff I can't buy there. Then I'll go to Iceland when the freezers running low. Tesco's have recently brought in their Discount Brands as well, and they are just as cheap as Aldi, and just as good. I just can't see the point in spending 99p on a 2l bottle of branded lemonade, when I can buy Aldi's own for 37p. I buy stuff when it's on offer, and then may even be able to go a week or so without a big shop if things are a tad tight.
Last night, Kayleigh was eating out, and Charlie had an early night, so me and DH treated ourselves. We had sirloin steak, chips, onion rings, grilled tomatoes and peas. The steaks were £2.39 for 2 from Aldi, the chips were Tescos own brand (37p for 1kg), onion rings from Iceland, tomatoes from the garden, and Aldi peas. I bet the whole meal cost less than £3, but it was absolutely beautiful!
Your 'friend' sounds like she needs to justify herself, and show that she's going okay for money now after her previous history. You are a bigger person than I am for forgiving her. Don't know if I'd have been so understanding.
