Getting a massage: Adjusting pressure

🇯🇵 [いらっしゃい。] is what staff say to welcome you into a shop or salon; customers normally don't say it back. You can just reply with [こんにちは。] or a small nod.

💬 [こちら] is a polite way to say [this way / here]. You'll hear it a lot from staff: [こちらへ] means "this way," and [こちらです] means "it's here/this one."

💬 [どうぞ] is a very flexible polite word for inviting someone to go ahead. You'll hear it with movement like [こちらへどうぞ。] and also with offers like [お座りください、どうぞ。]

🇯🇵 This is a standard staff phrase when guiding you somewhere, so no response is required beyond moving or giving a quick [はい。]. It's polite but completely routine.

💬 In [お願いします], the [お願い] part comes from a noun meaning a request or favor. You'll also see it in set phrases like [お願いがあります。] for "I have a request."

💬 [します] is the polite form of "do," but in [お願いします] the whole phrase works like "please." You can't translate each piece too literally there; treat it as a set expression.

💬 [お願いします。] is one of the most useful all-purpose polite phrases in Japanese. It often means "please," but more literally it's closer to "I'm asking for your help/service," so it fits naturally in shops, clinics, and salons.
