GYMPIE'S new $10 million Sunshine Mitre 10 store passed its first test on Saturday, accommodating the thousands of people arriving for the grand opening.
The streets around the warehouse were gridlocked for most of the day as customers arrived in droves to check out the state-of-the-art store and meet the stars from the hit Nine Network TV show The Block.
Sunshine Mitre 10 chief executive officer Darren Jordison said the number of people at the opening was a real surprise for the organisation.
"It was awesome," Mr Jordison said.
"We are not exactly sure how many people were in the store, but there was thousands, that's for sure.
"It's fair to say it exceeded expectations."
Mr Jordison said they expected a lot of people in the store for the opening because his team had put a lot of work into the day and the cast of The Block were going to be on site, but the response by the people of Gympie was overwhelming.
He said the store had handled the influx of people well.
"We still have a few little teething problems to sort out over the next few weeks, but the majority of customers were very happy."
He asked customers to be understanding while they worked on bedding down the operations of the new store.
"Our priority is to keep customer service high," he said.
Mr Jordison thanked TV personalities Ben Dark, Scott Cam and the cast of The Block for attending the opening.
He said they were very professional and humble in their dealings with the people of Gympie.
