I'm after some tips to help me explain to her how the more lager I drink with my top-up card on Saturday the more money I can save. It seems simple to me. I save 10% on every pint = 36p. Therefore if I put in some effort & manage 10 pints I stand to save £3.60 but if I only manage 5 pints I only save £1.80. She just can't seem to understand that by drinking more I'm helping us both by the saving I've made. Women huh?
