We carried on out in the open pretty much as usual in the southwest corner.
Noticed that fan noise from kitchen was annoying.
Southeast corner was occupied when we got there.
Consider getting that corner next time.

The "group" that reserved the meeting room had only one person.

inherent benefits of metric system
    different kinds of units are coordinated
    most kinds of units have only one name
        neverminding scaling prefixes, if there is more than one name for a
        kind of unit, they are related by a power of ten
            e.g., 1 erg == 1e-7 joule; 1 dyne == 1e-5 Newtons
            compare to 1 mile == 5280 feet and 1 foot == 12 inches
