I know it’s on me to ask - but it really irritates me to be given a card machine to tap that doesn’t show the amount unless you ask for it. Tapping on the end of the machine is a real design fault imo.
I’ve just bought a hot chocolate in a train station queue in a rush and as I walked away, I realised I’d tapped without seeing amount and with no receipt either - now unnecessary stress as I’ll have to check my account on the laptop when I get home (I don’t bank on my phone).
I’m sure it’s all fine but mistakes do happen and the system should not make it this easy to tap your card without seeing how much you are paying. At least, for now, it’s not possible to take more that £100. Grrr.
