The first time, I had emailed ahead asking what would be required to have a shower.

That resulted in a sign with my name.

This time, she just happened to get on the escalator beside me, so I said hi.

The first time I met a YEG concierge was because I said "good morning" or something when DrunkCargo and I were walking away from the lounge. She said hi, I guess looked back, saw an SE tag, and then engaged us (and immediately knew which SEs we were).

I find being friendly is all it takes.

Heck, the YYZ TB MLL agent today was a former concierge (senior enough to get the easy jobsl now). She didn't seem to recognize my face, but as soon as she took my BP, she mentioned she remembered me. And she said I was always pleasant. I'm not sure I agree with that, but I'll take the compliment
