A bar owner in Limerick says some people 'get shirty' when they are being asked for their Digital COVID-19 Cert.
Last week the HSE said it carried out hundreds of checks and reported very high levels of compliance.
Of 628 checks by the HSE, 74% were found to be compliant.
However a sample of 12 premises visited by the Irish Mail on Sunday this weekend found 80% of pubs and restaurants are not fully checking the certs in line with Government guidelines.
Just two out of a dozen pubs visited - less than 20% - asked to see a COVID Cert and cross-checked it with photo identification.
Fiona is the owner of Bobby Byrnes pub in Limerick. She told Lunchtime Live her staff have been met with confusion.
"We're checking COVID passports, ID, we're taking contact tracing, if you don't have a reservation already we're taking your name and number as a walk-in.
"But interestingly, we're finding we're getting on a daily basis people querying why we're still checking them - and getting a little bit shirty with you that you're checking their COVID passports.
"They're saying 'Why are you still doing this? You're the only ones doing it'.
"I don't know if people are just chancing their arm or what are they doing.
"But every day you will get somebody querying why you're checking it, and 'Are you really going to check it' or 'Are you seriously asking for that?'
"And that's what they're saying to you".
Name and shame?
She says they have taken on three extra staff specifically for the purpose of checking the certs.
"Every day people will query why we're doing it".
Asked if a 'name and shame' system should be brought in for non-compliant premises, Fiona says she's not sure that would help.
"There's days you struggle to have somebody on the roster to do it, but you have to.
"So is it a case that businesses don't have the staff to do it, they don't have the extra bodies?
"That is a massive crisis for our industry.
"Naming and shaming? I don't know - I'm just not somebody for naming and shaming. I think our industry has struggled enough.
"And there are so many discrepancies between hotels, restaurants, bars, nightclubs that a lot of the regulations don't make sense.
"But we're happy to do what we've to do, it means we get to keep the door open, keep staff safe and keep the customers safe".
