This.Working as receptionist easily nets you about 5-7 order for 3-4 fatigue. Pretty good trade and safe too.
Once you've secured level 1, you can keep the game going by doing the Receptionist job first, then beating as many enemies as you can on level 2. You should end up with net positive daily order gain. However, you'll probably need to throw in Bar sidejob in there to have any sort of income to buy edicts.
Some people dislike the bar sidejob however, and it more easily leads to passives and thus to Karryn becoming sluttier. You'll still want to clear level 2 in a timely manner.
