Swimming

My participant and I have been taking part in an Over 50s swimming group for the last three weeks at the local pool. MY participant is a really good swimmer.... Me not so much but we ve both been enjoying it. When we got there today there was a bit of a problem.... Someone in the group had complained to the manager that I was nt over 50 and they didn't think I should be allowed to take part. Even though I explained I am supporting my participant (aged 77)they said I could go in today but I wouldn't be able to carry on in the group. We were both a bit surprised by this....and have decided to move our swimming to the earlier open swimming session... Hopefully it will be a bit more relaxed?
