Last week I stopped at services and ordered in Costa two coffees. One Caramel Cappuccino (£3.89) and one Speciality Vanilla (£3.99). When I got to pay and bill was £8.18 I figured something must have gone wrong since it should not exceed £8. It turns out they have charged me Cappuccino (£3.59) + Caramel (£0.50) and another Cappuccino (£3.59) + Vanilla (£0.50) that totalled up to £8.18.
I then asked is there a difference in preparation of drinks (Caramel Cappuccino vs Cappuccino + Caramel and Speciality Vanilla vs Cappuccino + Vanilla), and there was no difference, they are exactly same drink that are being charged differently depending on how cashier feels like.
Are they allowed by law to charge different prices for same things?
