Admin worker Hollie Hodges was enjoying a day in Weymouth, Dorset, with her husband Craig, 32, and their seven-year-old daughter Lola when they noticed the odd behaviour.
Hollie, 34, recorded the footage on September 6 and said: ‘We were really shocked by what we saw. It was a really drunk gentleman on the beach being quite loud and weird.
‘Then he slept on the beach and he had sand all over his face and he was stumbling around looking a bit lost, so I started recording.
‘I thought he was going to do something funny and then he just started urinating.
‘After a while I thought he was going to walk to the sea, but he just stopped right there.’
The footage shows the man staggering to a group he had nothing to do with and get down on all fours before moving, almost dancing, while trying to look under their towel.
Put off by his antics , two women and a child, quickly moved away.
Hollie continued: ‘He was in full view, there were quite a few people who saw it – it was the talk of the town that day.
‘There were children around and people were shocked.
‘He went up to a family after he finished, they weren’t there with him – he just stumbled over the women and fell over.
‘I have no idea what he was doing. I think he didn’t know where he was – he didn’t say anything to them. It looked like he just wanted a hug or something.
‘He downed a whole bottle of vodka. You shouldn’t get that drunk, especially if you’re prone to not knowing what you’re going to do.
‘It’s antisocial behaviour isn’t it, and shows a lack of consideration for everyone else.’
