Abandon lots of rubbish? Waiter would like you to do that! (5,1,3)

I believe the answer is:

leave a tip

'waiter would like you to do that' is the definition.
(you might leave a waiter a tip)

'abandon lots of rubbish?' is the wordplay.
'abandon' becomes 'leave' (to abandon something is to leave it behind).
'lots of rubbish?' becomes 'a tip' (a rubbish tip).
'leave'+'atip'='LEAVE A TIP'

I've seen this clue in The Telegraph.
