Ilya-Dinis. Kolomiets and Koryakov

You work in a restaurant as a waiter, you served customers and when you were free, you were called to a table where there were two guys, you went up to take the order, a few minutes later, when the order was ready, you brought it, as you understood, the guys at the table were called Dinis and Ilya, a few minutes later you brought the bill, you took it and saw a note with a number, you threw the note away, in the evening when the work was over, you went home, in the dark, someone pinned you against the wall and said
D: Why did you throw away my note?))
I: didn't even give me a chance :(
