Dreadful scam in hotel that may take your money (4,7)

I believe the answer is:

slot machine

I'm a little stuck... Click here to teach me more about this clue!

'may take your money' is the definition.
I can't tell whether this definition defines the answer.

'dreadful scam in hotel' is the wordplay.
'dreadful' is an anagram indicator.
'scam'+'in'+'hotel'='scaminhotel'
'scaminhotel' anagrammed gives 'SLOT-MACHINE'.

'that' is the link.

Can you help me to learn more?

(Other definitions for slot machine that I've seen before include "2 8 [CASINO GAME]" , "Coin-fed device" , "One-armed bandit" .)
