What is cup sleeve event?

As an AI language model I don't have access to real-time events. However, generally speaking, cup sleeve events are a popular marketing strategy for coffee shops and cafes where they distribute reusable or disposable cup sleeves that bear the branding of the establishment or a specific campaign. These cup sleeves are designed to fit over take-out coffee cups and serve as a protective layer that makes holding hot drinks more comfortable. The event can include special promotions and discounts, interactive activities like photo booths or art installations, and may be held in coordination with an environmental cause to encourage customers to reduce waste. The aim of such events is usually to attract new customers, show appreciation to existing ones, and increase brand awareness.
