Taxi queue hoggers

If you've ever queued in a cab line before, you might be familiar with people at the head of the queue who 'graciously allows' you to board the cab before them because their spouse/friend(s)/children are "not here yet and I'm waiting for him/her/them". In a nutshell, these are the kiasu people who have been tasked to standby for a quick getway taxi by their family or friends.

While I'm rather OK with such people, there was a particular case this week that really irked me:

Venue: Tanglin Mall taxi stand
Time: Night
Irritants: A family of 3 (mother + 2 kids) which stood before us.

When a taxi came, the mother suddenly turned to the couple *behind* me and my wife, and beckoned to them to take the cab ("You can go first; I'm not in a hurry. You have a kid with you."). OK, they had a child in a pram, but who gets to decide if a couple with a baby in a pram has a higher priority than a man with a pregnant wife?

When the next cab came, I noticed that the same lady at the head of the queue did not make any attempt to board it, so I asked her politely, "Excuse me, are you taking that cab?". And she had the cheek to smile and reply, "No, I'm waiting for my husband".

Jeez...
