Fact:
In hotels, especially in
Act Now:
Ask these anxious waiters to wait till the glass gets completely empty. Ask if a bottle/jug of drinking water is available. It saves additional water to be used for washing used glasses.
Benefits:
1. Main benefit is saving most valuable thing for human life, the drinking/edible water, which is getting scarce across many cities/states/countries.
2. Another benefit is that you help save some polluting fuel* from burning by municipal authority for purifying water.
3. One small benefit is you save your own money paid as tax to authorities by saving additional water from purifying process. This saved money might be mobilized towards some other work by the authority.
4. One of the hidden advantage is you are not interrupted in between your important meeting or romantic chats frequently! ;)
*Fuel used for purifying in any form is normally polluting fuel, whether directly or indirectly. How? Electricity may have been used for the purpose, right? Ya, right. But again, generating this electricity itself is a polluting activity.
