Strip clubs can operate at all hours, depending on regulations and revenue. It is a common business practice to have a reduced door charge or no entry fee at all during daytime. Clubs that are open for more than just the nighttime hours may incorporate a staggered or shift work schedule for their entertainers and staff. External factors, such as location and public perception, have some impact on business, but the essential draw of the strip club is the live entertainment. Because of negative perceptions of the adult entertainment industry, many clubs engage in public displays of charity to generate goodwill. VCGH clubs, in order to be good corporate citizens, actively sponsor and participate in local charitable events and contribute to local charities. Some clubs also register their business entities using benign names, so that they appear to be businesses unrelated to the sex industry on receipts and financial statements, and as a means of discretion. Cameras (including camera phones) and other recording devices are often banned from strip clubs to "protect the identity of the women working there and to spare the blushes of men caught on film attending the club".
