The fan -- who goes by @dopekid_23 on Instagram -- was apparently chasing down Efron in hopes of getting a Snapchat video with him, but accidentally dropped and shattered his iPhone in the process. When the actor saw what had happened, he offered to buy him a new phone.
"Zac is definitely one the most humble celebrity I have ever encounter as well as [his costar] the rock," Ahmed captioned a video of he and Efron on Instagram. "Today while running after his car after he was taking break from shooting his new movie bay watch, I ran after his car with no care in the world."
"My phone fell on the ground and shattered completely," his post continued. "Zac said, 'Dude did you're phone just break?' He allowed me to take a video with him, He allowed me to come on set to meet him properly. And also Bought me a brand new phone. Which was $949.99 retail."
Judging by his social media post, Efron was just as stoked about the fan encounter.
"This is what I love about my fans - when they get excited, but @dopekid_23 actually smashed his phone while chasing me for a snapchat - that's dedication so I'ma hook you up with a new phone my brother!" he shared on Instagram. "To all my fans out there holdin it down - love and respect. And be careful with your phones ?"
Ahmed later took to Instagram to let everyone know that the actor had, in fact, kept his promise.
"What a f**king honor bro, you stuck to you're words and got me a brand new phone," he wrote. "@zacefron you truly are inspiring to ur fans. Very appreciative indeed thank you man."
"You don't understand how this meant so much to me bro," he continued in another post. "Last thing on my mind was for you get me a new phone because I ran after you're car. I knew the risks I was taking. Thank you once again I will never forgot this moment."
