I recently realised I am guilty of this. As someone who is connected to the internet 24/7, whether actively or just contactable via notifications/emails/texts via web etc, it still does genuinely surprise me when people ask for your payment details to pay, and then you hear nothing for several hours/days. This is often compounded by several other bods offering to buy as well, but you want to give the original dude a chance.
As above, tho, I realise this is more my issue from assuming everyone else has their johnson plugged into the cloud 24/7.
Not really sure where I am going with this, but just an observation I observed while waiting in a phone queue.
