Indeed. But there are also delays that cause good feelings.
I still remember the POS in my previous employers cafeteria. It had something like 100-200ms delay in processing a contactless payment card. It felt like an order of magnitude faster than any grocery store (exact same POS device). It was always very satisfying to pay for lunch. By the time you brought the card to the reader it felt like it was already printing the receipt.
I always wonder how it was so fast and if it was just some random dev optimising some obscure edge case.
