senior citizen forced to stand in queue while purchasing milk bags

Many people in panaji prefer to collect their milk bag from the local seller daily or a few times in a week.
Usually there are only a few people purchasing the milk, so most milk buyers do not have to waste much time to pay the money and collect the milk bag
However, once when there was a lot of rain, senior citizens were forced to stand in a queue for a long time, to purchase the milk bag
It is very inconvenient, and they feel tired. Their family members are also worried when they do not come home quickly after purchasing the milk bag
