Animation Sequence

Hi. I want to make an event that on timer(once per hour) a person with food will enter the room where players sits and put the food on the table.
So I have a rigged character and animations for carrying food and talking, food 3d model. But how do I combine these animations, how to do I make it walk for say 5 steps straight, then 2 steps to the left, then put the food on the table, then say something. How do I make it work? Help please!
