For those of you who have, then you must know that you need to specify how many seats required at the time of booking, for example, if there are 4 of you, then you’d fill in the number of seats field as 4 and the screen will show the 💺 💺 💺 💺 where you‘d be sitting.
Let’s say there are 2 additional friends that reach out to you last minute just before you confirm the booking. You would then change the number of seats to 6. What would happen on the screen is that it would just add 💺 💺 to the existing row where your four seats were and now it would just show 💺 💺 💺 💺 💺 💺.
