There were no protests from owners of stores selling cold drinks, as thirsty demonstrators caused a boom in business. But other outlets, such as mobile phone stores, saw a drop in sales as marchers crowded around the front of their stores to get to the march. About half of the drinks on sale at one 7-Eleven outlet in Causeway Bay had been cleared out by 4pm. Ho Tang, the 58-year-old owner of a snack shop in the district, said business jumped by about a third. He made about $4,000 selling drinks, cigarettes and sweets. 'If I didn't have to keep the shop open, I would have marched today,' Mr Ho said. The hostility towards the chief executive could be felt among his customers, he said.
