I suspect we've all seen the news that JL partnership bonuses are much reduced this year. This bbc article implies whilst things have been bad JL has had a particularly bad few months www.bbc.co.uk/news/business-51750252 Waitrose profits have not been hit in the same way. As always there's a number of causes but I haven't been in my local JL store for months now, basically not since the unisex changing room news. I have kept going to Waitrose as it's been the only supermarket within easy reach 
I think this might be a good time to get in contact with JL customer services to explain why we no longer want to use their stores. For many of us they will now be able to see the change in our purchasing record at an individual level.
I've no wish to see the partnership go out of business but I'm struggling to get past the 'ick' factor of not knowing who might be in the cubicle beside me and what they might be doing and I don't want to do business with companies who show contempt for my viewpoint
