TVs in restaurants, cafés and bars generate business. Customers who are alone, for example business travellers stopping for lunch or coffee, are likely to visit more often and stay longer, spending more. The downside is that the sound is annoying to others and changes the ambiance or conflicts with the often carefully programmed background music. Subtitles are OK, but still a poor option.
LimeOnAir solves the problem. The customer just uses the App on their iPhone or Android device.
