After the riot and the cleanup, a lot of shops are boarded up and the securing was still going on yesterday, while the first windows were being rapaired as well. Smashed up shops included charity shops, and small shops, besides the big chains, phone and betting shops.
Some shops were boarded up, but already open for business again, which seems to indicate that while they had glass damage, the interior wasn't damaged too badly and they had enough stock left to continue trading.
