not a food delivery guy but~
During a vacation my cousin& I were on last year,
we went to this internet cafe slash sandwich shop, and there was this extremely cute Korean guy there hahaha. I dont think he usually works there.. it's a family owned place so he had to go in to fill in someone's shift I guess.. and like.. he brought his cute little doggy along XDD my cousin&I played with it for a bit while I waited for my food. he took FOREVER to make it and it was just a simple sandwich. hahaha not that I was complaining cause we got to talk to him more. he was so cute..! omg.
then his brother came in later who was even CUTER and aaaah I was so flustered and tongue tied LOL D;
he asked us to watch the dog for him (:
then he let me have my sandwich for free (: he wouldn't take the money. I felt bad though so I tipped him $5 in the tip bucket thing XDD it was funny cause then his brother& he started fighting over the tip. he was like she gave it to ME! this is my shift..! blabhlah lol. I didn't notice what was going on until my cousin told me later.
then they had leftover smoothie after making someone's order so they were like "free smoothie~ does anybody want it?"
We didn't want to take it cause we didn't want to be like .. leechers haha since I already had a free sandwich. But when these guys went to go take it.. the brothers were hesitant about giving it to them.. and looked in our direction cause I guess they meant to give it to us ? so we took it :]
It made our day so much better cause the previous day, the concert we were aposed to go to got cancelled (the whole reason why we took the trip in the first place

; ) we had a nice conversation with them . i even got pics of his dog.. I was trying to take pictures of him WITH his dog but like.. my camera was being a doodybutt at the time lol. he was even sort of posing for it, but i missed it :[
We came back the next day hoping to see them again (our excuse was to see his cute dog again.. rofl XD ) but instead, their dad(?) was there. And he was rewatching the tape recordings from the day earlier so we were like oh crap ..

what if they review today's recording and sees us coming back looking for them? so embarrassing

good thing we had to fly back home that same day so we never saw them again.
I'm kinda regretting we didn't say anything that day. asked for their #, e-mail, anything. it would have been fun to become friends with them or something :]]
so yeah there's my long winded encounter with cute food service guys LOL~
well anyway.. XD good luck! hehe
