Yesterday my wife was craving for coconut rice, so we decided to have a late lunch at Rosa’s Thai Cafe – which many say is the best thai in London. We had been there a few times already, and as always the food was excellent, but this time there was something new.

The bill came in a tablet (see picture below). And the app, enabled by Yumpingo, not only had the detailed bill, but also a thumbs up/down against each item, as well as a final quick survey to collect our feedback.

This made our experience at Rosa’s even better. A paperless transaction is a great innovation and, in my opinion, should be mandatory (mainly for environmental reasons). And the willing to collect customer’s feedback is still something most companies, let alone restaurants, are still not keen to do.

But in the middle of all this, something made me raise the eyebrow. The first question in the short survey was “How likely are you to recommend Rosa’s Thai Cafe to a friend or relative” and the answer had a 1 to 5 scale!… When this was clearly a NPS question, which should have a scale between 0 and 10.

A few months ago, in my blog post Does changing NPS scale make sense? I raised the question around NPS, and if it would make sense to have a European variant where 6-7 were Passives (rather than standard 7-8) and 8-10 were Promoters (rather than standard 9-10).

What didn’t cross my mind was having a different scale of 1 to 5, rather than the 0 to 10, set by Fred Reichheld, Bain & Company, and Satmetrix; Accepted and adopted by the majority of CX practitioners and specialists; Ensuring that the market had a standard and consistent way of measuring NPS.
