First off, did you call and ask about an "appointment" to have someone show you the storage lot? If not, why not? That's the proper procedure. Expecting someone to drop what they're doing, perhaps leaving the phones and/or office unattended while doing so is IMHO, unreasonable. Setting an appointment eliminates this issue.
Second, why care who's parked next to you. You might rent your space because of the awesome Prevost parked there, only to find out that converted school bus parked two rows over actually belongs there....when we say stop and smell the roses, we don't mean looking down our noses at them...just sayin....Dennis
