Purpose of any language is to express yourself, feelings, messages, and to pass on information to others. As long as that purpose is met, no matter how you spell. India is a nation of over 14 regional languages, and people who are on travel, should get to know things; and english is only known language all over country ( at least to some extent). Many of the hordings must be in some village or remote places and this is their best efforts to convey things. So, take it easy.
