To be able to access the workshop you need to make sure that you didn't give Lucy work from the Guildboard or else she'll lock herself in there for the reminder until you call her back, some days you'll see Lucy in her Workshop so be sure to visit her in the morning... as for the Morning Quickie, you need to meet Lucy in her room in the morning and you'll see her on her bed stretching, go speak with her for the Morning Quickie.. there are specific days that Lucy will be either in her room or her workshop... probably, you'll just have to visit both when it's morning
