The only pubs that I frequent that take contactless are Spoons. I agree that is quicker. most however have one card machine that is usually in use and waiting to authorise. Meanwhile the rest of us wait to be served.
You've obviously never used contactless.
The whole point is that there is no authorisation, it takes one second to put your card against the reader and it is done. Zero hold up to anyone and no fannying around with trips back and forth to the till and counting out change. Add to that the idiots that take a week to get their wallet out and start counting out the right money
No I use contactless regularly and agree it is fast and efficient. Only ever seen it in Wetherspoons pubs, no other pubs that I use.
