<p>You may not have noticed this, but the escalators on the underground MRT in Bangkok have signs telling you not to walk and to hold onto the handrail.&nbsp; But on the BTS skytrain, they tell you to walk on the left and stand on the right.</p> <p>Certainly the vast majority of passengers seem to be ignoring the signs.&nbsp; This could be the confusion of having different systems in the same city, but I suspect it’s just the regular scoff-law attitude you get round here.</p>
