Recently I saw in a Restaurant in Goa, India, stainless steel bottles ( insulated inside to keep hot and cold temp.) filled with water provided on the tables with glasses. The bottles are narrow -mouthed ( maybe about 30 mm dia) and about 1000 ml capacity ( almost 14 to 16 inches tall). I feel that the risk of Food Hazard entry in this type of bottles is high unless you have a strong standard operating procedure for washing, inspection and stock rotation. Normally I see only glasses in restaurants for provided drinking water in India. Wide mouthed Water jugs are provided in the rooms. I would like the members" views. .
