The publicity stunt, aimed at promoting the mobile phone network’s new custom plans, is taking place on 6-7 September at Observation Point. Thousands of 100g bags of sweets will be up for grabs.

Passers by can pick their own choice of sweets from the wall if they post a picture of themselves in front of the Pick ‘N’ Mix wall using a specific hashtag, #O2CustomPlans.
