Do we need a gambling licence?

[MustangLady]

Hi.. in small cafe business and thinking of putting a fruit machine in corner of our cafe for Customer use. We won't be having a big payout, just a maximum of �5 (five pounds) .. in this instance would we need a Gambling licence? Also if such a small winning payout, is there a minimum age limit to usage of this machine? Any advice would be grateful.... thanks ML
