Backlash from frustrated concertgoers continued to come in today on social media, as people who worked both inside and near the venue are calling Beach Blast 2016 extremely challenging and 'ridiculous'.

An estimated 30,000 people attended Beach Blast 2016, a country music concert held in Parlee Beach on Saturday.

Aric Salsman, a security guard, said not enough security was hired by the organizers.

"We did the best we could with the numbers we were given," said Salsman. "Ultimately there's a certain point where we couldn't really maintain 100 per cent of what we were told to do."

Salsman said security spent a good amount of its time stopping people from jumping the fence to get inside the venue, and from getting into the VIP area.

Safety concerns were also raised after two people climbed the speaker towers.

"Somebody had mentioned to the organizers that it would have been a good idea to maybe almost double security. I personally think that would've been a good idea," said Salsman.

Staff working at nearby stores in Shediac were also feeling the effects of the large crowds that took over Parlee Beach, with people coming to their stores because of an apparent lack of toilets on site.

Kristina Wylbur, assistant manager at the Shediac Corner Store said she doesn't think organizers planned for such a large number of people.

"There was garbage across our entire parking lot," said Kristina Wylbur, assistant manager at the Shediac Corner Store. "We had people peeing behind the store. We had lines for each bathroom all day."

Wylbur said people were getting very rowdy, and there was even an incident with one of the concertgoers who came to her store.

"She was waiting in the line for the bathroom and it was so long of a wait she just couldn't hold herself. She went to go to the back of the store and then ended up peeing in our garbage cans."

Venue not equipped to deal with 30,000?

It's unknown whether the reported 30,000 people attending Beach Blast 2016 was more than organizers were expecting. CBC has tried several times to contact Embou productions, but there has been no response.

Some who attended the concert told CBC they had to wait up to two hours to get a bottle of water or food. Long waits were also reported to get inside the venue.

"I had to wait in every kind of lineup to get whatever I wanted," said Leita Petrie. "I was more or less at a concert for 8 hours, and probably more than half was in lineups."

Salsman said he felt so bad for some in the crowd that he did whatever he could to help.

"There's a lot of times where I had a guard just watch my spot for a second so I could grab a customer's money, run to the VIP water area, buy as much water as I could and then ran back because their children were dehydrated."

The RCMP had about 30 officers around the concert venue, and arrested 17 people for public intoxication.

They also say many were drinking on the street and officers did seize some alcohol.

It took about two hours to clear the area after the event, with the crowd blocking off some streets in Shediac temporarily as they left.
