My bank recommended only using the ATM's inside the branches as they can keep an eye on these. The ones in the street are regularly tampered with.
The machines inside the bank (at least at Barclays) have a higher withdrawal limit - and staff on hand to help if anything goes wrong. The ATM's on the wall outside are not their responsibility - if one swallows your card or otherwise misbehaves you'll still have to phone the card company in the usual way - the bank branch staff can't help.
