About this location

A few stories people tell about this place

1. At night, when Diamond Shamrock gas station closed its doors, a soft humming sound would occasionally drift through the air. A delivery driver first noticed it one foggy morning, thinking it was just an oddity of the old pumps. As days passed, more people started noticing the hum—even customers filling up their tanks. Soon enough, it became a local joke: if you heard that eerie noise, better grab some snacks because the gas station was closing soon! One evening, after dark, a delivery driver parked his truck next to the pumps and asked aloud, ‘Who’s still here?’ Only to hear a friendly voice from inside reply, ‘Just me, keeping the place open for you!’ Turned out, it was just the owner’s parrot, repeating everything he heard.

2. In the early morning hours, a delivery driver pulled up to Diamond Shamrock for coffee and noticed something odd in one of the gas pumps’ nozzles—a tiny plastic unicorn, its horn glowing faintly under the streetlight. As he leaned closer, another small toy emerged from a different pump—this time it was a smiling teddy bear waving hello. The delivery driver laughed, paid for his coffee, and drove off, muttering that maybe Diamond Shamrock had a secret stash of toys for lucky customers.

3. At dawn, a delivery driver pulled up to Diamond Shamrock and noticed something strange—a faint scent of freshly baked cookies filled the air. Curious, he peeked inside and saw an old lady in a plaid dress stirring something on the counter. ‘Morning,’ she said with a smile. ‘Fresh batch just came out—would you like one?’ The delivery guy shook his head politely but couldn’t help taking a bite. Turns out it was the best cookie he’d ever had, and from that day on, Diamond Shamrock became famous for its morning treats.

4. At dawn, a delivery driver pulled up to Diamond Shamrock and noticed something strange—an eerie whiff of freshly baked cookies wafting from inside. Curious, he cracked open the door—a soft glow illuminated the interior, and there stood an old gentleman in a plaid shirt, humming gently as he placed warm cookies into a paper bag. ‘For you,’ he said with a smile, handing over one cookie. ‘They’re my secret recipe.’ The delivery driver took a bite and nearly choked—he’d never tasted anything so good on a gas station snack rack. From then on, whenever anyone asked where to find the best cookies around town, they’d reply, ‘Head to Diamond Shamrock at dawn!’
