Bitcoin Cash still has a block time of 10 minutes, which is makes it terrible for micropayments.
To be fair, any cryptocurrency is terrible for micropayment unless it has very fast block time (e.g. 10 seconds). People and cashier don't want to wait 10 minutes (or even 30 seconds) to wait a transaction confirmed.
With 2-of-2 multisig address where both merchant and customer park the same amount fast block time isn't necessary, even 24 hours blocks will work just fine.
