But chef Oliver Dunne was less than impressed when 30 diners failed to show up for their Mothers' Day bookings at his exclusive restaurant.
Oliver works at well-known eatery Bon Appetit in Malahide and, despite being booked out the door on Sunday, the restaurant was filled with nothing but empty tables when diners failed to turn up for their meals.
Frustrated, Ireland's youngest Michelin-starred chef took to Twitter to air his dissatisfaction with the no-show diners.
"To the 30 people who confirmed and no-showed today – well done. I'd say your mother is proud," he wrote.
Sunday's empty tables left Oliver's restaurant down €1,000, and he says the problem of missing diners is costing him around €2,000 every week. This amounts to €104,000 a year – a substantial loss for any business.
Fellow restaurateurs were quick to empathise with Oliver. One commented: "Ridiculous. Plus how many did you have to turn away because of these confirmed reservations?"
"Unbelievable in this day and age," another wrote. "Booking deposits should be compulsory for groups over six."
The Restaurant Association of Ireland has estimated that no-show diners cost the service industry around €300 million annually.
And Oliver wants to highlight the issue. "Just to clarify my objection in the 'no-show tweets' is to create awareness, not to name and shame.
"Why on earth can't people just pick up the phone and call is beyond me," he said.
"It's just ignorance, and it's time that credit card bookings were introduced, like they are in other countries."
