Many music lovers waited in long lines to get into the TRNSMT music festival at Glasgow.
Tickets holders posted on social media that they had been waiting hours in the hot sun for security checks to be completed at the entrance of the site.
Some claim it took over two hours to give water to the crowd.
Organisers apologized for the "longer than usual" waiting time.
One fan sent a tweet to the organizers: "Please tell us that you are refunding at least partially." This is a living nightmare. I paid PS200 for the privilege of looking at people's dead trims for three hour.
Another tweet: "The TRNSMT queue is a joke. Literally, it was a mile long on either side. There are very few stewards, and it takes three hours to get into @TRNSMTfest. It's all going to be sorted.
Some ticket holders claimed that some people tried to leap over fences.
Many people were disappointed that they missed the bands they'd come to see.
Saturday's lineup featured Fontaines DC, The Snuts, and Foals. Fontaines DC was headlined by The Strokes.
On the first day of the festival, Sam Fender, Nile Rodgers, and chart-topping Scot Paolo Nutini performed on the main stage.
On Sunday, Lewis Capaldi, who will be the headliner, will perform on the last day of the three-day festival.
Another social media message was: "Three Hours in this horrendous line!" People getting stuck in bars and fighting breaking out. Shambles."
Another fan complained that queues were "absolutely ridiculous." There are no stewards, there is a surge forward every time we move. It's unsafe and it's not safe. No one is doing anything to stop it.
TRNSMT spokesperson said that there are longer waiting times than usual for festival-goers.
"Our welfare teams are giving water to people queuing, and we're trying our best to get everyone inside security and inside as safely and quickly as possible.
"We are grateful for the patience shown by those who wait, and we ask anyone in need to contact the Stewards or Welfare Teams."
