Requires good memory and high discipline-15 rules and instructions to obey plus no talking in the hallway.
May irritate Mr.Ralf easily-I got capital letters and exclamation marks, sounds like scolding, when I forgot to follow one of the rules.
Facing deficiency- Not enough hot water to shower 3 people or have to wait long time. Also hand-wash soap is diluted.
Treated impolitely- When asking for borrowing microwave for 1 minute, get refused(which is OK) but told I asked something "unusual".
