I agree what a shambles at the tills for us customers and also the staff who are trying to work this unwieldy app voucher scheme. I spent 22 minutes trying to log onto the O2 service at my local Waitrose, while facing a poster highlighting the importance of the customer satisfaction to Waitrose-ha, ha. I then gave up, as shopping should be a pleasant experience and this definitely was NOT-it deserves a zero minus. I also feel that the scheme now discriminates against all those without smart phone. I was a regular customer but will be transferring my weekly shop to M and S especially now the free paper offer has also met an untimely demise.
