Accidentally adding on to tabs

[sde1000]

A fairly common pattern seems to be:

• Customer starts a tab.
• Staff member adds the customer's name to the tab.
• Staff member fails to use "Recall Transaction / Hide current transaction"
• Staff member goes back to the till and adds items for another customer
• Customer pays for previous customer's tab plus their own transaction
• Staff member has to refund original tab and start again

Can we add a prompt that a tab may not have been hidden correctly? We would be looking for:

• A transaction with a note
• Has been recalled implicitly by a staff member tapping in, not explicitly with Recall Transaction
• It's been more than a couple of minutes

This might save us some Square fees!
