One barbershop owner has criticised suggestions that his industry may have to start checking Digital COVID-19 Certificates.
Sam Donnelly, owner of Sam's Barbers in Dublin, was responding after the Chief Medical Officer said he was in favour of the certs being used in hairdressers and gyms.
They are currently only needed for the hospitality sector and for international travel.
The possible extension of their use comes as COVID-19 cases continue to rise.
Dr Tony Holohan said on Wednesday people may soon need a digital cert to go to the gym or hairdresser.
"We look at all of that on an ongoing basis, and we'll give advice on that if we think that's appropriate.
"But... we'd have no reason to have any concern about that, and nothing to stop people in those sectors saying 'That's an additional security and safety measure that I can put in place to protect my staff, protect my customers' - that would be a good thing", Dr Holohan added.
But Mr Donnelly told The Pat Kenny Show this approach makes no sense.
"It's complete tripe to be quite honest.
"I've worked under the Return to Work Protocol with our industry and our leaders as regards the make-up, the hair and beauty industry as a safe environment - and we've done it.
"We're in this pandemic almost two years, we've had employees test positive and their colleagues have not tested positive.
"Our environment is a safe environment - and if vaccinated people are the only ones allowed get haircuts, do you really genuinely think that non-vaccinated are not going to get a haircut?
"It's going to increase the black market economy, which has already got ahead of everyone on this stop-start of eight months being closed".
He says uncertainty around such issues means joined up thinking is not there.
"It's hard enough for city centre salons without people in the offices not being in town.
"But now you're going to say that you can't do the non-vaccinated either?
"I want clarity, like everybody else, because they're not giving anybody any clarity.
"They're tripping themselves up - one minute they do one thing, the next minute they do another.
"When you put it together they're not making sense".
