Recently there have been a lot of abandoned trolleys strewn about Catford (mainly from the big Tesco).

I have been reporting these to Tesco via Twitter whenever I see them and I have also enquired about what Tesco is doing to prevent people wandering off with their trolleys however the response was fairly lacklustre - essentially they said that they lock up their trolleys at the end of the day but beyond that there is nothing that they can do.
That said, I did actually see the following notice in Tesco at the weekend so perhaps they are taking it seriously:

Finally, there are several apps that are available which can be used to report these issues:
Love Clean Streets

If you see any trolleys please do report them via one of these means so we can get them off our streets and back to the store ASAP.
