Nothing better engages clients than a full keg of microbrewed beer in the office lobby. This one, from Danby, even rolls, so everybody in a multiparty class action case can partake. Just pour a draft from the easy to use tap, close it off, and roll it across the lobby to whoever wants some.
Don’t skimp, though, with plastic Solo red cups or the like. Use real pint glasses. This is a law office during the weekday, not a college frat house on Saturday. Duh.
