I’d like to open a coffee shop next to the Ticketmaster offices, and if any of the bosses come in to buy a drink I’d charge them for the coffee, plus insurance in case they drop it, plus a transaction fee, plus a handling fee for me to hand their coffee to them over the counter. The coffee that should cost £3.75 will set them back £17.89. Seems reasonable, no?
