It's hard to name just one but probably any "away" business lounge where you have been offered the facility but when you arrive:
1. Nowhere to sit because the lounge has the same space/people ratio as the public waiting areas in the airport
2. No food other than "snacks"
3. Disinterested staff
4. Internet/phones/fax "temporarily" not working (VS in Boston for about 18 months)
5. No national papers
6. Strange location 20 minutes away from the gate..or
7. Landside location so the gauntlet of security must still be run (VS at Newark or JFK..can't remember)
