Her job is to burst their balloons and tell them that straws suck - but it's all for the good of the planet.
Marine biology doctoral student Refilwe Mofokeng, 29, is determined to stop restaurants, retailers, industry and the public from further polluting our seas with litter. She has already persuaded the John Dory's restaurant at Wilson Wharf's, Durban, to stop giving customers birthday balloons.
Thanks to Mofokeng, the outlet has also promised to collect all its used plastic straws instead of throwing them in the trash. The straws will be delivered to artists at Durban's BAT Centre to create an enormous plastic whale - yet another initiative from the woman who is determined to make a difference to the environment. The whale will be used as part of a December holiday awareness campaign aimed at removing plastic from the ocean.While Mofokeng is at the forefront of the war against plastics, she is certainly not fighting alone.
Cape Town's Two Oceans Aquarium has launched efforts to create awareness about the problem - something that spokeswoman Renée Leeuwner said many South Africans simply weren't aware of.
It is estimated there are more than 150 million tons of plastics in the ocean. By 2050 there will be more plastics than fish - by weight - in the ocean.
It is illegal to release balloons, she says, but few people are aware of this.
The National Environmental Management Act imposes a duty of care on every person to take reasonable measures to avoid causing significant pollution or degradation of the environment.
"When former Springbok Joost van der Westhuizen died, his fans advertised a mass release of balloons in his honour," said Leeuwner.
"When the impact of balloons on the environment was explained to J9, his foundation, they immediately shut down the release."
She said that social media was a key player in creating much-needed awareness."When Bob, the green turtle, was brought to us in November 2014 for rehabilitation, he pooped out pieces of balloons.
"We circulated a picture of the waste that came out of him on Twitter. Our picture was tweeted and retweeted by individuals and organisations around the world," she said.
Mofokeng - a University of KwaZulu-Natal student who is doing her doctoral thesis on microplastics found in makeup, toothpaste and detergents - set up an NGO last year to create public awareness of the amount of pollution, specifically plastics, in the ocean.
"I started it after the big storms in 2016. I saw footage of all the plastics washed out to sea and thought: 'Enough is enough.' We can't keep complaining and blaming others. We need to take responsibility."
Thanks to people like Mofokeng, public awareness is growing.
Eddie Moyo, the manager at John Dory's at Wilson's Wharf, said they had been distributing up to 200 balloons a month. These have now been replaced with lucky packets.
"Currently we cannot stop giving out straws, but we are collecting them for the sculpture. The artists will need thousands of straws," said Moyo...
