I do my best to avoid being caught in the rush hour commute on the buses/tube/trains etc, but from time to time it does happen when I have my 10mth DS and occassionaly 6yr DD.
At none rush hour times I find people are either helpful or politely uninterested. In rush hour we get tutted and huffed, glared at and subjected to rude, passive-aggressive comments. The whole tone is generally aggressive and unpleasant.
It's public transport, we have as much right to be there are any otherpaying traveller!
For the record, I used to work in the City (not a banker ) and I am well aware of the stresses and strains of work and the commute and I don't think excuses being so rude to people/children who happen to be taking up space that you want.... grrr
