Reminds me of a wee Tesco whisky story. A couple of years back, Tesco, all of a sudden and unknown to the brand in question, whapped 1.50 off the price of a bottle in the run up to christmas, as is their want. Someone hadn’t done their sums, and it backfired, costing Tesco money in the end up.
Tesco then go back to the brand (who haven’t been able to negotiate a rise in their price with Tesco for 4 years) and tell them that they have to pay a ‘levy’ to Tesco. Said brand tell Tesco to whistle, Tesco then say, ‘oh well, we’ll be immediately removing your whisky from our shelves!’
Levy paid. Over a barrel (awful pun I know!). Not really relevant to the thread at all, but I found it interesting.
