Procrastinate in Lumiose City, and do stuff like traveling or working at the Hotel, and you will get perks, such as a discount on stones, discounted Taxi rides, entry into exclusive diners, and free soda! (Lied about the last one) Speaking of the hotel, you can advance in the attendant ranks and get larger compensation per job. I forget the first few, but you can get 10,000, 20,000, and eventually 50,000 per job.
