Bad habits in public. Watch out for top answers!

I conducted a survey of "bad habits" people exhibit in public. This survey focused on simple things people do, for example, in public transport, shops, waiting areas, etc. 

I asked men and women of different age groups who work / study in different areas. The result showed a long list of what irritate people, but below are the top 10 answers. 

In public, many people do not like it when, sitting or standing close to them, you do the following:

1. Eat apple loudly 
2. Chew gum loudly
3. Comb your hair 
4. Pick your nose without using a handkerchief or tissue
5. Cough loudly without shielding your mouth
6. Sneeze without shielding your mouth/nose
7. Yawn without shielding the mouth 
8. Spit right in front of them
9. Blow your nose right in front of them without using a handkerchief or tissue
10. Pick your teeth with a toothpick

It is interesting to note that there are certain things we do, unconsciously of course, without realising that they really irritate those standing or sitting close to us. 

It is true that we should not allow others to dictate how we live our lives, but we have to be cautious of what we do and take other people into consideration at all times.
