Interesting topic to raise.

Personally I've never had much problem per se, yes there are slippery halls but not enough for me to worry a lot about it. I can understand the rant, and it's not great that you are now avoiding halls with slippery floors but on the other side of the coin it's good that you are not taking the risk if there is a possibly of injuring yourself.

I think one of the problems here, is actually your shoes. They are made by Yonex. Yonex don't really specify what type of floors said shoes are made for. I've found this out whilst looking at Yonex shoes at their stall at the All Englands. Was looking at an expensive pair and asking a few questions and basically they are good shoes, but not for halls. More for the floors like the All England's courts, rubbery or carpet type. 

This issue has also risen recently for me so it's funny that you should bring it up. I played at another club for a change and a couple of the kids there were struggling with the floor and had a mat that they used in between points to “clean” the soles of the shoes. And you guessed it, they were an expensive looking Yonex shoes!

Now, I'm not saying that all of Yonex shoes are bad, as quite a few people at this club had Yonex shoes and only a couple of them were experiencing problems with the floor. What I am saying is, some shoes are better for all floor surfaces than others even if it is made by Yonex and advertised as a badminton shoe. How hard is the bottom of the shoe? If it's very hard like a pair of very cheap shoes you can get at a discount store, then maybe they don't suit the hall.

I used a pair of Prince squash shoes, for two reasons. I have narrow feet, and they are better soled for all types of floor surfaces.

Maybe play the halls that you struggle with, with a different pair of shoes and see how you get on?

Hope this helps in some way, it's only my opinion, but I think Yonex should highlight little things like this but there you are 

Many of the leisure centres I play matches in are shared with schools and very rarely mopped. 
I turned up to play a county game the other week in our home venue and proceeded to mop all 4 courts myself because I wasn't prepared to allow my team to risk their bodies on it. 
I came to play at the same venue 4 days later and the floor was back to it's usual slippery state…

I use a damp beer mat as previously suggested, although i have seen tournament players spray their shoes with cheap hairspray to add a 'tack' to their soles.
