Ireland's move towards card and digital payments could see tips being moved away from staff.
One etiquette expert has said tipping in Ireland has become more common and is really about being respectful.
It comes after a sign posted in a restaurant window in the US state of New York reminded people to tip their waiters.
It read: 'Servers make the State minimum wage, which is $5.65 - most of it is taken away in taxes.
'They rely on your tips to make a living: when you don't leave a tip, they would have served you for the duration of your entire meal for nothing.
'Take care of those who take care of you'.
Brenda Hyland-Beirne is from the Irish School of Etiquette. She told Lunchtime Live we are generally very generous.
"The tipping etiquette in Ireland most of the time is quite generous - at the end of the day I suppose we're a fairly generous nation.
"Tipping is really being respectful to somebody, especially if you've got good service.
"And I do think most people in Irish society we do tip, and rightly so.
"Now if your service wasn't great, you might hold back - but generally speaking it's 10% to 15%."
But Brenda said as more people pay with card or digital payments, the tip can get lost.
"We also have to consider another thing that happens: we now can give tipping through the card.
"And often... it isn't being given to the staff in a lot of cases.
"So we have to be careful that we do tip the staff, I think, and continue to do that - and in generous fashion".
And Brenda said there isn't much comparison to the US, and that the restaurant in question may have done themselves a disservice.
"We're in a different situation entirely, I think that restaurant in the US certainly shot themselves in the foot.
"[They] have exposed themselves: because it's pretty appalling when you think $5.65 [with] taxes taken from it - they are certainly relying on tipping without a doubt.
"Whereas we have the living wage - I think it's around €10.20 - and of course if you're living in Dublin, it's relative isn't it?
"But certainly tipping has become far more common in Ireland as time has gone by".
'I completely depended on tipping'
Moe, who is originally from the United States, worked in hospitality here. She said she never made a living wage.
"I made €25 a shift, and so I completely depended on tipping. I found that most Irish people tipped for the most-part.
"We were next door to a big hotel, and when the Americans came in it was great - because you knew they'd tip well.
"But they were also extremely demanding, so that's part and parcel of it.
"I understand why people would resent tipping, and if people were paid a proper wage then tipping wouldn't be such a deal.
"But restaurants really struggle, and labour is one of their main costs, and the restaurant industry is notorious for being difficult and restaurants fail all the time.
"I think it really comes down to somebody needs to pay the staff; and whether that's going to be the restaurant or the punter.
"Most servers, certainly that I know, they're not making a lot of money - a lot of them are the working poor.
"And I understand why people don't want to tip, but if you're not tipping the only person that's really going to feel it and be affected is that low-wage worker".
While Lucy, who previously worked in the restaurant trade, said: "When you get a tip you feel appreciated, you feel 'I've done my job well'.
"And it just makes you feel better - and you do work hard, restaurant work is hard".
