I had a better than usual SC experience using the ATL Terminal A second floor last Friday afternoon. The agent not only scanned me in but also reconfirmed the gate, and told me what time I should leave the SC. On my way out, a different agent wished me a pleasent flight.
This may be SOP, but I rarely get it
Oh and the bartender made me the tastiest spicy bloody-mary double limes included - all from scratch! (The SC in SFO had it all premixed already and it definitely didn't taste as good)
