A patron at the outlet said: 'This nudist was seen trying to buy coffee at McDonald's but ended up causing quite a stir. My friends and I were there when we saw the guy coming towards McDonald's.'
'We saw him nude,' he added.

The patron, Sean, said that he lingered around outside for about 10 minutes before departing from the premises.
