@adsactly, great and valid points you have made.
While it might not be possible to eliminate the possibility of eating out totally, i think its best to consider some factors you have highlighted before taking to eating at a particular restaurant although compromise on personal hygiene can't be completely ruled out and with time, we can reduce to the barest minimum the issue of eating out.
Thank You
Yes, it is a gradual process..we can reduce until we can stop..
