Some possible openers for you...

Light & witty:
"Funny how I always run into you here… it’s almost like you work here or something."

Playful twist:
"Wow, we keep bumping into each other at this place. It’s starting to feel like destiny… or maybe just your shift schedule."

Cheeky but harmless:
"I swear, every time I come here you’re at the window. Either this is fate, or you’re following me."
