The bus depot symbolism sounds like you are dealing with a situation in your life that is difficult to be patient with or forces you to be patient. The old woman you seek help from may reflect your search for passive experience or experience with putting others first. You never find the woman that was with you originally because it may represent how you feel you've lost a method or resource you had. All the different kinds of food at the end may represent different idea.
"To dream of waiting at bus stop represents an unpleasant or powerless experience you are expecting to happen. Waiting for a situation to occur that you don't believe will feel good." From: http://www.dreambible.com/search.php?q=bus+stop
OP: "please let me know the meaning"
Rainbow Gryphon on October 13, 2013: "the meaning of a dream has a lot to do with what's going on in your life, and that's something only you can really know"
Ed on October 21, 2013: "dreams are personal and the symbols that your subconscious uses can be entirely different from someone else"
So you have to do your own work to interpret (I prefer to say "distil the message of") the dream. The book "Inner Work" by Robert A Johnson has fifty or sixty pages on dream interpretation and I've found it very interesting and useful. The process is time-consuming, the more so as the dream will be telling you something that you're not already consciously aware of and/or you're resistant to or defended against. So the 'obvious' (personal) interpretation is unlikely to be the right one, still less he 'comfortable' personal interpretation.
